The Ultimate Fantasy Football Rules Guide (Best, Worst & Fun League Settings)

Most fantasy football leagues don’t fail because of bad owners—they fail because of bad rules.

The difference between a league people tolerate and one they obsess over usually comes down to settings. The right rules create strategy, fairness, and year-round engagement. The wrong ones lead to frustration, imbalance, and owners checking out by midseason.

This guide breaks down the best fantasy football rules to use, the worst ones to avoid, and creative ideas that can make your league more fun—whether you’re starting fresh or fixing a league that’s gone stale.

What Are the Best Fantasy Football Rules?

The best fantasy football rules are the ones that reward skill, reduce randomness, and keep owners engaged all season long. Settings like FAAB waivers, superflex lineups, and median scoring give every team a fair shot while increasing weekly strategy.

What Are the Worst Fantasy Football Rules?

The worst rules are the ones that introduce unnecessary randomness, limit strategic decisions, or create frustration between owners. Trade veto voting, poor waiver systems, and overly complex scoring are some of the most common mistakes.

What Are the Most Fun Fantasy Football Rules?

The most fun fantasy football rules are the ones that spark league rivalry, reward bold strategies, and keep everyone laughing. Unique punishments for the last-place finisher, rivalry-week matchups, and customized draft-order challenges add a layer of personality that transforms a standard league into an annual tradition.

Rules for the Three Core League Styles

League Type	Core Focus	Recommended Rules
Casual/Home Leagues	High Engagement & Fun	Draft Order Challenges, Weekly High-Score Payouts, Rivalry Weeks
Competitive Redraft	Skill & Risk Mitigation	FAAB Waivers, Third-Round Reversal, Game Against the Median
Dynasty & Keeper	Long-Term Strategy	Player Contracts, Taxi Squad Snatching, Late Trade Deadlines

Best Fantasy Football Rules That Improve Your League

If you want a league that feels competitive, fair, and worth paying attention to every week, these are the types of rules that actually move the needle.

FAAB Waivers: Free Agent Acquisition Budget

FAAB (Free Agent Acquisition Budget) completely changes how owners interact with the waiver wire. Instead of a traditional rolling priority where the worst teams get the first pick automatically, every owner starts the season with a virtual budget (typically $100 or $1,000) to blindly bid on free agents each week.

• Pros: Gives every owner a fair shot at top free agents. It eliminates the frustration of losing out on a season-defining waiver target just because of an arbitrary draft order or waiver position.
• Cons: Requires active management and basic math skills; casual players may feel overwhelmed if they exhaust their budget too early in the year.
• The Blueprint: Give owners a $100 budget and allow $0 bids. Allowing $0 bids ensures that teams who completely run out of money can still fill empty roster spots caused by late-week injuries or heavy bye weeks.

Superflex Lineups: Elevating the Most Important Position

In standard fantasy formats, elite real-world quarterbacks are drastically devalued because you only ever have to start one of them. A Superflex roster configuration solves this by adding an extra flex spot where you can start a Running Back, Wide Receiver, Tight End, or a second Quarterback. Because QBs carry the highest baseline point floor in the game, every team will actively try to start two of them every week.

• Pros: Instantly fixes positional value. It makes mid-tier starting NFL quarterbacks highly valuable trade assets and demands intense draft-day strategy.
• Cons: Severely punishes owners who fail to secure viable starting quarterbacks, leading to major frustration if a league member gets hit hard by injuries.
• The Blueprint: If you run a 12-team Superflex league, impose a strict maximum roster cap of 3 active starting NFL quarterbacks per team. Since there are only 32 starting jobs in the NFL, this prevents a single owner from hoarding signal-callers and starving the rest of the waiver wire.

Third-Round Reversal (3RR): Leveling the Draft Board

In a traditional 12-team snake draft, the owner who lands the 1.01 spot holds a massive, statistically proven advantage. They secure a tier-one superstar, pick again at 2.12, and get another premier asset at 3.01. Third-Round Reversal completely alters this math. The draft snakes normally for the first two rounds (1 to 12, then 12 to 1), but at the start of Round 3, the order flips. The owner at 1.12 picks first in Round 2, Round 3, and Round 4, while the 1.01 owner doesn’t see the board again until 3.12 and 4.12.

• Pros: Perfectly counterbalances the overwhelming advantage of owning a top-three draft slot, resulting in highly balanced, competitive rosters across the entire league.
• Cons: Can be highly confusing for casual owners during their first draft cycle, and it requires pre-draft communication so the top-slot owners aren’t blindsided by the sudden wait.
• The Blueprint: Use 3RR as a mandatory setting for any high-stakes league or startup dynasty draft where multi-year roster value is established right out of the gate.

Game Against the Median: Overcoming Schedule Bad Luck

There is nothing more frustrating in fantasy football than scoring the second-highest point total of the week, only to lose your matchup because you happened to play the single highest-scoring team. Playing a “Game Against the Median” gives every team two potential standings decisions every single week: one head-to-head matchup against their scheduled opponent, and one matchup against the league’s weekly scoring average (the median).

• Pros: Drastically reduces bad luck. If you score in the top half of the league but lose your head-to-head game, you still walk away with a 1-1 week instead of a devastating 0-1 loss.
• Cons: Dilutes some of the classic, Monday-night head-to-head drama and trash-talking that defines casual home leagues.
• The Blueprint: Implement this setting on platforms like Sleeper with a single toggle. It is the single best way to ensure the most skilled, high-scoring teams actually make the playoffs, rather than teams that simply lucked into a weak schedule.

Multiple Flex Spots: Demanding Deeper Roster Decisions

Traditional fantasy leagues rely heavily on rigid, ancient roster templates like 2 RB, 2 WR, and 1 Flex. Upgrading your league to include multiple regular flex spots (such as starting 2 RB, 3 WR, and 2 or 3 Flex positions) shifts the focus from top-heavy star power to total roster depth.

• Pros: Rewards owners who scout deep sleeper options and excel at working the waiver wire. It also opens up massive flexibility in draft strategy—you can build a viable team by heavily stacking wide receivers or loading up on depth.
• Cons: Greatly thins out the waiver wire, making it incredibly difficult for struggling teams to find immediate, plug-and-play starters during heavy bye weeks.
• The Blueprint: When expanding to multiple flex positions, simultaneously expand your total bench size to at least 7 or 8 spots. Owners need the runway to hold developmental players and backup stashes if they are required to field deep starting lineups.

Tiered PPR Scoring: Balancing Positional Value

Standard Point-Per-Reception (PPR) scoring was originally created to make wide receivers competitive against bell-cow running backs. However, in the modern, pass-heavy NFL, traditional PPR has created a massive imbalance where short, zero-yard checkdown passes to a running back are rewarded just as heavily as a tough, contested first-down grab by a wideout. Tiered PPR solves this by altering the reception bonus based on position—typically awarding 0.5 PPR for Running Backs, 1.0 PPR for Wide Receivers, and 1.5 PPR for Tight Ends (often called Tight End Premium).

• Pros: Naturally rebalances the fantasy landscape to match modern NFL usage, instantly making the historically weak tight end position an elite, first-round strategic asset.
• Cons: Adds a layer of complexity to the scoring system that makes it harder for owners to quickly calculate mental projections while watching live games.
• The Blueprint: Tie tiered PPR directly to a Point-Per-First-Down (PPFD) structure. Awarding points for actual real-world production rather than empty, negative-yardage catches is the ultimate sweet spot for a modern, competitive league.

Weekly High-Score Payouts: Sustaining Active Engagement

In almost every fantasy league, two or three owners will fall out of playoff contention by November. Once a team hits 2-8, those owners often check out, stop setting their lineups, and inadvertently hand easy wins to whoever they play late in the year. Introducing weekly cash payouts for the highest-scoring team completely eliminates this late-season apathy.

• Pros: Keeps every single owner hyper-engaged through Week 14. Even if a team is mathematically eliminated from the playoffs, they still have a real, weekly financial incentive to submit a competitive lineup and work the waiver wire.
• Cons: Requires a slightly higher initial league buy-in from the start to fund the weekly prize pool without draining the grand prize for the league champion.
• The Blueprint: Take $5 or $10 from everyone’s initial buy-in to create a dedicated weekly high-score fund. If your league buy-in is $100, allocate $15 or $20 to the top-scoring team of each individual week, leaving the remaining pool for the top three playoff finishers.

These rules don’t just sound good—they directly impact how competitive and active your league feels week to week.

Worst Fantasy Football Rules Commissioners Should Avoid

Some rules seem harmless but quietly ruin leagues over time. They create frustration, kill trading, or make outcomes feel random instead of earned.

League-Vote Trade Vetoes: The Collusion and Bias Trap

In the early days of fantasy football, allowing the entire league to vote on whether a trade should pass was standard practice. Today, veteran commissioners know it is a toxic mechanic. When you allow owners to vote on other teams’ trades, they rarely vote based on actual collusion. Instead, they vote out of pure self-interest—vetoing a trade simply because it makes a competitor’s roster stronger or because they are jealous they didn’t land the player themselves.

• Pros: Gives passive owners a sense of control over the league’s competitive balance.
• Cons: Sparks immediate league drama, destroys active trading markets, and encourages petty voting habits that alienate owners who negotiate fair deals.
• The Blueprint: Strip the league of its voting power entirely. Move to a system where all trades are instantly processed or subject only to Commissioner approval. The commissioner should only step in and reverse a trade if there is clear, undeniable evidence of collusion (e.g., a 2-8 team dumping an elite player to a 8-2 team for a backup kicker).

No Waiver System (First-Come, First-Served): Rewarding Free Time Over Strategy

A first-come, first-served free agency system means that the moment a player is dropped or a backup running back hits the news wire due to a practice injury, anyone can log in and immediately scoop them up. This turns your fantasy league into a contest of who can stare at NFL news alerts the fastest, rather than who can build the best football strategy.

• Pros: Creates a chaotic, hyper-reactive environment that rewards the most obsessed owners who monitor breaking news 24/7.
• Cons: Severely penalizes owners who have rigid work schedules, family commitments, or live in different time zones, making the league fundamentally unfair.
• The Blueprint: Implement a standard waiver processing window. All unlocked free agents should be placed on waivers until a designated morning later in the week (typically Wednesday), forcing owners to submit claims via a structured priority or FAAB budget system.

Week 18 Championships: Letting NFL Rest Weeks Create Chaos

The absolute worst time to play a fantasy football championship game is the final week of the NFL regular season. By Week 18, elite NFL teams have frequently locked up their playoff seeding or division titles. As a result, head coaches routinely bench their superstar quarterbacks, running backs, and wide receivers to keep them healthy for the real playoffs.

• Pros: Extends the fantasy football calendar by one extra week, satisfying owners who want to play as long as possible.
• Cons: Ruins months of hard work. An owner who dominated the regular season with elite players can lose the championship game simply because their stars are wearing baseball caps on the sideline while their opponent wins with third-string backups.
• The Blueprint: Lock your league’s championship game into Week 17. This ensures that the vast majority of NFL teams are still fighting for playoff spots or divisional seeding, ensuring that your league’s title is decided by actual starting NFL talent.

Overpowered Defense Scoring: Unpredictable and Broken Swings

Defense/Special Teams (D/ST) units are inherently volatile, but default platform scoring settings often exacerbate this variance. When a defensive scoring system weights single-play anomalies—like a random blocked field goal or a lucky fumble recovery in the endzone—as heavily as a 100-yard rushing performance by a running back, the system is fundamentally broken.

• Pros: Provides casual, low-scoring teams with a “lottery ticket” chance to pull off a massive upset purely on defensive variance.
• Cons: Undermines strategic roster construction by allowing an unpredictable defensive score to erase a perfectly executed offensive game plan.
• The Blueprint: Dial back defensive scoring triggers. Shift the focus toward rewarding sustained defensive skill, such as points scaled to actual points allowed and yards allowed, rather than over-weighting volatile defensive touchdowns. Better yet, look into removing the D/ST position entirely in favor of an extra regular Flex spot.

Unlimited Keepers with No Draft Cost: Breaking Long-Term Balance

Keeper leagues are a fantastic bridge between redraft and full-blown dynasty, but allowing owners to keep an unlimited number of players year after year without a scaling draft penalty quickly breaks a league. Within two seasons, the top two or three teams will lock down all the elite, tier-one talent, leaving the bottom-tier teams with absolutely no path to recovery during the draft.

• Pros: Simulates the feel of managing a real franchise for the top teams who lucked into drafting young superstars.
• Cons: Kills league longevity. Once the casual or struggling owners realize they have zero mathematical chance of drafting an elite player, they check out and abandon the league.
• The Blueprint: Attach a hard draft-capital penalty to every kept player. For example, if an owner wants to keep a player they drafted in the 5th round the previous year, it should cost them a 4th-round pick this year. Limit total keepers to 2 or 3 players max, and cap the number of consecutive years a single player can be kept.

No Trade Deadline: Late-Season Roster Manipulation

Running a league without a trade deadline opens the floodgates for severe roster manipulation in November and December. When a trade deadline does not exist, teams that have been mathematically eliminated from the playoffs are highly susceptible to trading away their top-tier assets to championship contenders in exchange for future draft picks, lopsided player packages, or off-platform favors.

• Pros: Keeps the trade market open all year long, allowing playoff teams to cover for late-season injuries.
• Cons: Invites severe ethical dilemmas and creates a direct threat to the competitive integrity of the playoff bracket.
• The Blueprint: Set a firm trade deadline that aligns with Week 12, 13, or 14 of the NFL season. This guarantees that trades can only occur while the vast majority of the league is still actively fighting for a playoff spot, keeping everyone honest.

Overly Complex Scoring Systems: Confusing and Frustrating Owners

A rulebook should never look like a corporate tax code. While custom scoring can be fun, over-complicating the system with hyper-specific fractions—such as awarding 0.23 points per passing completion, 0.5 points for a tackle for loss, or separate bonuses for 40-yard plays—makes it impossible for owners to intuitively follow a game.

• Pros: Appeals to math-heavy, analytical owners who want to quantify every microscopic detail of a football game.
• Cons: High barrier to entry. It paralyzes normal owners, makes it incredibly difficult to evaluate basic trade offers, and strips away the simple joy of watching box scores.
• The Blueprint: Stick to decimal-based, universally understood scoring formats (like standard half-PPR or full-PPR) and limit your custom rules to one or two high-impact variations like Point-Per-First-Down or Tight End Premium. If your owners can’t calculate a score in their head while watching a game live on Sunday, the rule is too complex.

Avoiding these is just as important as choosing the right rules.

Fun & Creative Fantasy Football Rules to Try

Once your league foundation is solid, this is where things get interesting.

These rules aren’t required—but they can make your league more unique, memorable, and fun.

Guillotine Format: The Ultimate Survival Elimination

The Guillotine format changes the core objective of fantasy football. Instead of playing head-to-head matchups, the entire league competes in a massive weekly battle royale. At the end of each week, the single lowest-scoring team in the league is completely eliminated. Their entire roster is then forcefully released into the free agent pool, triggering a chaotic waiver wire feeding frenzy for the surviving owners.

• Pros: Creates unmatched, high-stakes drama every Monday night. It keeps the waiver wire incredibly electric all season long as elite superstars suddenly become available.
• Cons: Brutal and unforgiving; a single fluky, low-scoring week in September completely ends a owner’s entire season.
• The Blueprint: Start this with an 18-team league if possible, so you have exactly enough teams to eliminate one owner per week until Week 17, leaving the final two teams to fight for the championship. Use a 100% FAAB bidding system to manage the dropped players fairly.

Vampire League: One Draft Outcast vs. the World

In a Vampire league, one owner is designated as the “Vampire” before the season begins. The Vampire is completely banned from participating in the snake draft—they must build their starting roster entirely out of the undrafted players left on the waiver wire. However, the Vampire has a terrifying superpower: every time they win a head-to-head weekly matchup, they get to forcibly steal a player from their opponent’s starting lineup and swap them for someone on their own roster.

• Pros: Introduces a fantastic, asymmetric gameplay mechanic that creates a built-in “villain” for the league to rally against.
• Cons: Extremely difficult for the Vampire to win early in the season, and it can cause massive frustration for casual owners who hate losing their drafted superstars.
• The Blueprint: Give the Vampire the permanent #1 waiver wire priority all season long to help them stay competitive, and rule that the Vampire can only steal a player who plays the exact same position as the player they are trading away.

Empire Leagues: The Ultimate Test of Back-to-Back Dominance

An Empire league operates like a standard keeper or dynasty league with a massive financial twist. A portion of every owner’s annual buy-in is split into two separate prize pools: the regular seasonal payout, and a separate, rolling “Empire Jackpot.” The jackpot pot cannot be won by a single-season champion; it continuously accumulates year after year until one owner successfully wins the league championship back-to-back years. The moment someone wins consecutive titles, they trigger the Empire clause, take the entire jackpot, and the league completely dissolves and restarts from scratch.

• Pros: Creates an incredible multi-year narrative and a massive financial bounty that discourages owners from abandoning a struggling roster.
• Cons: Can take five, ten, or more years for someone to trigger the jackpot, meaning a lot of cash remains locked up in a rolling fund for a long time.
• The Blueprint: Allocate exactly 20% to 30% of the annual buy-in pool directly to the Empire pot. Keep the funds in a secure, transparent platform like LeagueSafe so every owner can watch the bounty grow over the years.

Double-Header Weeks: More Action and Less Schedule Variance

To inject more action into the regular season while reducing scheduling bad luck, introduce double-header weeks. During these specific weeks on the calendar, every team plays two separate head-to-head matchups simultaneously against two different league opponents.

• Pros: Doubles the weekly trash talk, creates massive data swings in the standings, and quickly separates the elite rosters from the pretenders.
• Cons: Can feel visually overwhelming on older platform interfaces that don’t display side-by-side matchups cleanly.
• The Blueprint: Instead of making the entire season a double-header, schedule exactly two or three designated “Double-Header Weeks” during heavy NFL bye weeks to force owners into deep roster optimization battles.

Rivalry Matchups: Building Custom, High-Stakes Storylines

Instead of letting a computer algorithm randomly generate your league schedule, a commissioner can manually construct a custom schedule centered around specific “Rivalry Weeks.” This rule pairs up natural rivals—such as college roommates, siblings, or the previous season’s championship finalists—to play each other during high-profile weeks of the season.

• Pros: Instantly elevates league engagement and gives owners a personal reason to trash talk and set optimal lineups, regardless of their record.
• Cons: Requires manual commissioner editing on the backend of the platform, which can be tedious to configure before kickoff.
• The Blueprint: Schedule a “Rivalry Week” for Week 1, and an identical rematch for Week 14 right before the playoffs begin. To raise the stakes, dictate that the loser of the rivalry matchup must pay an extra financial penalty to the winner or buy them dinner.

Captain Scoring: The Rotating Weekly Strategic Twist

Borrowed from popular daily fantasy (DFS) formats, Captain Scoring allows owners to designate a single player in their starting lineup as their “Team Captain” for that specific week. The designated Captain receives a flat 1.5x multiplier on all fantasy points earned during that game, but their negative points (fumbles, interceptions) are also multiplied by 1.5x.

• Pros: Introduces a highly strategic layer of weekly decision-making, allowing risk-tolerant owners to maximize a high-upside matchup.
• Cons: Can lead to massive, unpredictable point swings that result in frustrating losses if an opponent’s Captain unexpectedly scores three touchdowns.
• The Blueprint: Rotate the position eligibility each week. For example, mandate that Week 5 is “Wide Receiver Captain Week,” forcing owners to think critically about their pass-catchers rather than just automatically slapping the Captain tag on their quarterback every week.

Lottery for the Last Playoff Spot: Keeping the Mid-Tier Engaged

In traditional formats, the final playoff seeds are handed to the teams with the next best win-loss records. This rule strips that certainty away for the very last spot. If your league has six playoff seeds, seeds 1 through 5 are determined normally by standings. However, the 6th and final seed is awarded via a live lottery drawing among the remaining bottom-tier teams, with lottery odds weighted based on total points scored.

• Pros: Completely eliminates late-season tanking. Every mid-tier team remains hyper-focused on scoring maximum points down the stretch just to earn more lottery balls for a shot at the postseason.
• Cons: Can feel incredibly unfair to a team that finished cleanly in 6th place in the standings, only to lose their playoff spot to a lucky bounce of a lottery ball.
• The Blueprint: Only allow teams that finish between 6th and 10th place in the standings into the lottery pool, completely excluding the absolute worst teams to ensure a completely non-competitive roster doesn’t accidentally stumble into the playoffs.

The key is using these as enhancements, not replacements for strong core rules.

How to Choose the Right Rules for Your League

Not every rule fits every league.

Before making changes, consider:

• League experience level (casual vs competitive)
• Owner activity (daily vs weekly engagement)
• League goals (fun vs high-stakes competition)

The best leagues aren’t the most complicated—they’re the ones where everyone understands the rules and stays engaged all season.

The League Constitution Framework: Why Your Rules Need a Home

Having a great list of fantasy football rules is only half the battle. If those rules aren’t codified into a written, accessible document, your league is constantly one bad bad-luck bad-beat away from a total meltdown. Every league needs a League Constitution—a living, breathing document that serves as the ultimate authority when chaos inevitably strikes.

A written constitution isn’t about being overly bureaucratic; it’s about protecting the integrity of the league and saving the commissioner from endless headaches.

Preventing League Collapse: The Unwritten Disasters

When cash, pride, and decades of friendship are on the line, people get emotional. A platform glitch, an unprecedented NFL scheduling change, or a controversial mid-season trade can instantly tear a league apart if you don’t have a predetermined protocol. Your constitution should clearly outline how the league handles:

• Platform Glitches & Lineup Errors: What happens if a owner swears their phone crashed right before kickoff and they couldn’t bench an injured player? The constitution should have a hard rule (e.g., “Lineups lock at kickoff, no exceptions unless the owner texted the commissioner their intended change prior to the game starting”).
• Official Stat Corrections: ESPN, Yahoo, and Sleeper often process stat corrections days after a matchup ends. Your constitution should explicitly state that the platform’s official Tuesday or Wednesday final update is the law of the land, regardless of how heartbreaking a retrospective stat correction might be.
• Mid-Season Dispute Resolution: Define exactly how a dispute is settled. Does the commissioner have total executive power, or is there a co-commissioner or three-owner “league board” that steps in to review conflicts?

The Voting Threshold: Simple Majority vs. Supermajority

A common mistake rookie commissioners make is treating every rule change the same. If an owner wants to tweak the scoring for defenses, that shouldn’t require the same level of consensus as transitioning the entire league from a standard redraft into a keeper league.

To maintain stability, your constitution should establish two distinct voting thresholds:

• The Simple Majority (50% + 1): Reserved for minor, quality-of-life adjustments voted on during the offseason. This includes things like adjusting the trade deadline by one week, shifting kickoff times for the draft, or tweaking bench sizes by a single spot. If 7 out of 12 owners agree, the motion passes.
• The Supermajority (75% or Unanimous): Reserved for systemic, landscape-shifting changes that completely alter how owners value their rosters. Moving from a standard 1-QB league to a Superflex format, altering major scoring settings (like adding Point Per First Down), or increasing league buy-ins should require a supermajority (typically 9 out of 12 votes) or a completely unanimous vote. This ensures that a slim, temporary majority can’t hijack the long-term identity of the league.

How and When to Introduce Rule Changes

A fantasy football league should evolve, but how you implement changes is just as important as the changes themselves. Pulling the rug out from under your owners is a surefire way to kill engagement and invite mutiny.

The Golden Rule: Offseason vs. In-Season Changes

If there is one absolute, unbreakable law of commissioning, it is this: Never alter scoring settings, lineup configurations, or roster rules once the draft has started.

The moment the first player is selected on draft night, every owner has built a strategy based on the current rulebook. Changing a rule in Week 3—even if it seems like an obvious fix—will always inherently benefit some teams while penalizing others, instantly creating an environment of unfairness.

The Only Exception: The absolute only time an in-season rule change is acceptable is to fix a genuinely broken, game-breaking platform setting that was left on by mistake (e.g., discovering in Week 2 that a missed field goal is accidentally penalizing kickers -10 points instead of -1). Even then, this correction should require a unanimous 12/12 vote from the league to implement mid-season.

The Dynasty Grace Period: Planning for the Future

In a standard redraft league, you can completely overhaul your rules every August because everyone starts with a clean slate. In dynasty and deep keeper leagues, however, roster assets hold multi-year value.

If your league decides it wants to make a radical structural shift—such as adding a second regular Flex spot, transforming into a Superflex league, or implementing player contracts—you cannot implement it the following season. Doing so completely destroys the value of teams that built their rosters around the old settings (for example, a dynasty owner who traded away future draft picks to stack elite running backs because quarterbacks held low relative value).

For dynasty leagues, always implement a 1-to-2-year grace period for major structural shifts. If the league votes to move to Superflex in 2026, the change should not officially take effect until the 2027 or 2028 season. This gives every owner multiple draft cycles and trade windows to strategically restructure their rosters with the future rules in mind.
