Commissioner Managing a Collusion Complaint: How to Investigate Suspected Trade Collusion
The hardest commissioner situation is investigating a collusion complaint: unlike a scoring error (which has a factual right answer), collusion requires judging intent. Two managers who are friends may make a bad trade that looks collusive but was genuinely poor judgment. Two strangers may execute a trade that serves both parties legitimately but looks lopsided from outside. The commissioner must evaluate the full context — not just the trade — before reaching any conclusion.
The Collusion Investigation Process
| Step | What to do | Why |
|---|---|---|
| Receive the complaint in writing | Ask for specific allegations, not vague “unfair trade” claims | Specific claims can be investigated; vague ones can’t |
| Calculate the trade value objectively | Use a consensus trade chart on both sides | Quantifies the imbalance — 30%+ discrepancy warrants investigation |
| Review the context | Is the sending manager out of contention? Are the managers friends? | Intent evidence — lopsided trade + known relationship = investigation |
| Check for prior patterns | Has this pair made lopsided trades before? | A pattern changes the probability of intent |
| Investigate privately | Do not announce publicly until investigation is complete | Premature public statements create discord |
| Communicate the resolution | Notify involved managers before public announcement | Gives them a chance to explain before the league sees the ruling |
The Collusion Standard
True collusion requires both of the following:
- A value imbalance that cannot be explained by legitimate trade reasoning — not just a bad deal, but one that no reasonable manager would accept without an outside arrangement.
- A relationship or pattern suggesting the imbalance was intentional — not naive, but deliberate.
A lopsided trade between strangers may reflect bad judgment. A lopsided trade between roommates in week 14 with the playoff race on the line is much more likely to be intentional. Both criteria must be present.
Managers are allowed to make bad trades. A commissioner should not void a trade because one side got the worse value. The commissioner’s role is to prevent intentional competitive corruption — not to protect managers from their own poor decisions.
Worked Example: Two Investigations, Different Outcomes
Complaint A: Manager X (2–9, eliminated) trades his top WR to Manager Y (8–3, in first place) for two bench players. X and Y are known to be close friends. Trade value check: WR worth 2,500 points; return worth 800 points. 68% imbalance. Context: X is eliminated, Y needs a WR1 for the playoff push. Both conditions present: major imbalance + known friendship + timing advantage for Y.
Commissioner action: Void the trade. Issue a formal warning to both managers. Document in the league constitution.
Complaint B: Manager A (5–6, borderline) trades a WR2 to Manager B (7–4) for two RBs. Value check: WR2 worth 1,600 points; RBs worth 1,450 points together. 9% imbalance — within normal negotiation variance. No known relationship. Manager A believes the RBs give her a path to the playoffs.
Commissioner action: No action. This is a judgment call by Manager A that the field disagrees with — not collusion. Explain the policy.
Common mistake: voiding a trade because it is lopsided without meeting the full standard. Overturning legitimate trades creates more damage than the original trade — because now the commissioner has become the trade police, and every future deal the league dislikes becomes a collusion complaint.
After the Investigation
If collusion is confirmed: void the trade, restore both rosters, issue formal warnings, and document everything. If it is not confirmed: communicate the findings clearly and explain what the standard is — so the complaining manager understands the bar and the rest of the league sees the process was fair.
Evidence Checklist
Look for communication, repeated one-sided behavior, outside compensation, or a pattern that cannot be explained by normal roster strategy. Do not rely on screenshots from uninvolved managers without verifying context. If the evidence is weak, document the concern and monitor future activity rather than issuing a public accusation.
The commissioner should also separate trade-review standards from collusion standards. A trade can be unpopular and still valid. Collusion is a higher bar because the accusation damages trust.
