Commissioner Collusion Policy: How Fantasy Football Commissioners Handle Collusion
What constitutes collusion: collusion in fantasy football typically takes one of three forms — trade collusion (two managers trade undervalued players in a lopsided deal to deliberately help one team), game-throwing (a manager purposely sets a losing lineup to help another manager’s playoff or seeding prospects), and waiver collusion (managers agree not to bid on certain players so one can claim them at the minimum price). The key element is intentional coordination for competitive advantage — bad trades made independently, even clearly unequal ones, are not collusion.
Collusion Policy Quick Reference
| Collusion scenario | How to identify | Investigation approach | Mistake to avoid |
|---|---|---|---|
| Trade collusion | Significantly lopsided trade value between teams with misaligned incentives (e.g., eliminated team trades to playoff rival’s opponent) | Compare trade values with an external calculator; review trade history between the same managers; ask each for independent rationale | Reversing a trade based on calculator imbalance alone — lopsided trades by themselves are not collusion; intent must be demonstrated |
| Game-throwing (deliberate losing lineup) | A manager in a meaningful matchup starts clearly non-optimal players (injured starters, players not in the game, benched veterans) | Check if the optimal lineup was available; review the starting decisions with context (were injured players known before game time?) | Acting on suspicion that a manager is “tanking” without evidence of deliberate action — poor weekly decisions look the same as intentional losses from the outside |
| Waiver collusion | Two managers avoid bidding on each other’s target players in FAAB auctions despite both needing the player | Review FAAB bid history; compare with each manager’s roster need; look for patterns across multiple weeks | Assuming collusion because two managers never bid against each other — they may simply have different roster needs |
| Evidence standard | Pattern + communication records or admission | Circumstantial (two friends traded twice) is insufficient; require either admission or a pattern of multiple suspicious transactions | Investigating based on “everyone knows they’re friends” — social relationships do not constitute collusion evidence |
| Consequences (defined before season) | Proportional to severity: trade reversal for minor, disqualification or expulsion for confirmed intentional collusion | Apply consequences written in the constitution; do not improvise consequences after the fact | Expelling a manager based on a single lopsided trade without a pattern of behavior — the consequence must match the evidence |
| Announcement of investigation | Private — do not announce publicly until investigation is complete | Unfounded allegations made public damage innocent managers even if cleared | Announcing the investigation in the league chat before it is complete — public accusations cannot be unspoken if the allegation turns out to be wrong |
Building a Collusion Policy
Define collusion in writing. Your league constitution should define what actions constitute collusion — not just conceptually but with examples. Vague definitions lead to disputes about whether a specific action qualifies. Include examples: “A trade where one manager receives a player at significantly below his current market value in exchange for a player at significantly above market value between teams with misaligned incentives may constitute collusion.”
Define the evidence standard. Collusion investigations should require a defined evidence standard before consequences apply. Circumstantial patterns (two friends trade twice in a season) do not constitute collusion evidence — intent must be demonstrated. Define what evidence is sufficient: admission, communication records, a pattern of multiple suspicious transactions, or a combination.
Handling Collusion Allegations
Investigation process. When collusion is alleged, the commissioner should: (1) collect all trade history between the involved parties, (2) compare trade value using an external calculator, (3) check for prior transactions between the same parties, and (4) if possible, ask each manager independently for their rationale. Avoid announcing an investigation broadly — if the allegation is unfounded, public accusations damage innocent managers.
Consequences. Defined consequences are essential to fair enforcement — if collusion is confirmed, what happens? Common consequences include trade reversal, team disqualification, or expulsion from the league. Undefined consequences invite inconsistency and accusations of selective enforcement.

For related enforcement paths, read trade review process, trade veto policy, and rules enforcement. Collusion decisions need evidence standards, not just manager pressure.
