Commissioner In-Season Checklist: What to Do Every Week During the Fantasy Season
A well-run fantasy league feels effortless to the managers in it. That smoothness comes from the commissioner doing consistent, unglamorous work every week. Missing one week of monitoring can mean a dispute that drags on for three weeks. The checklist below is the minimum.
Weekly Commissioner Checklist
| When | Action | Why it matters |
|---|---|---|
| Monday (after last game scores) | Verify all final scores are correctly calculated; check that trades submitted before deadline processed correctly | Score errors happen; catching them Monday prevents mid-week disputes |
| Tuesday–Wednesday | Monitor waiver wire activity for unusual claim patterns; address any trade objections or disputes from previous week | Out-of-contention managers making unusual high-FAAB bids for a friend is a collusion signal; disputes should be addressed within 24h of submission |
| Thursday (TNF week) | Verify rosters are set for Thursday players before TNF kickoff | Once Thursday kickoff begins, lineup changes for Thursday players are typically locked — enforce this consistently; do not offer do-overs |
| Weekly | Monitor lineup activity — if a manager has not updated their lineup for 2+ consecutive weeks, reach out | Inactive teams hurt every opponent they face; early intervention prevents a ghost manager situation |
| Trade deadline | Set it and enforce it without exception; trades submitted after the deadline are rejected | Post-deadline panic trades destabilize the playoff push for everyone; exceptions invite appeals |
| Playoff seeding week | Verify final standings are correctly calculated; apply tiebreakers per your documented cascade; communicate playoff bracket immediately | Managers need to know their playoff fate immediately — delayed announcements create anxiety and speculation |
| Championship week | Double-check all rosters set, no scoring issues unresolved from prior playoff rounds, prize distribution instructions confirmed | The highest-stakes week of the season; any error here becomes your defining commissioner moment |
Handling Disputes In-Season
Set a dispute window: Disputes should be submitted within 24 hours of the issue occurring. A manager who waits until Week 10 to dispute a Week 4 trade has forfeited their right to dispute it in most reasonable rule sets.
When a dispute is submitted:
- Acknowledge it immediately (within a few hours)
- Investigate it thoroughly
- Communicate your decision clearly
- Apply the decision consistently — a rule applied to Team A must apply to Team B under identical circumstances
Lineup irregularities: Starting injured or bye-week players is common among less-engaged managers. Verify your platform’s automated rules are working. Whatever your policy on pre-kickoff substitutions, document it and apply it consistently.
Monitoring for Collusion
Watch for:
- Two specific managers making multiple trades over several weeks
- Trades that clearly benefit one side without plausible justification
- A manager who has announced they are dropping out but continues to make significant trades
When you see potential collusion: do not act immediately. Document what you observe, continue monitoring for a week, and then evaluate the full pattern. A single suspicious trade is often just a bad trade. A pattern is something else.
Playoff Week Management
Seedings and bracket: When the regular season ends, verify final standings, apply tiebreakers per your documented cascade, communicate the playoff bracket immediately, and confirm which teams have byes.
Championship week: Double-check: all rosters correctly set; no scoring issues from prior playoff rounds left unresolved; the champion is determined by the platform per the constitution; prize distribution instructions confirmed before the winner is announced.
End-of-Season Checklist
After the champion is determined:
- Distribute prizes within 7 days (or confirm timeline if using a third-party service)
- Send a season recap message — thank managers, acknowledge top performers, preview next year
- Collect interest for the next season before managers scatter
- Document rule changes discussed during the season for the offseason vote
- Save the final standings and league history somewhere permanent
The biggest commissioner challenge is keeping managers engaged between seasons. A brief end-of-season recap and an early next-season interest check goes a long way. Managers who feel the commissioner cares about the league tend to return.

Worked Example: Weekly Commissioner Routine
On Monday, verify scores and note any stat-correction risk. On Tuesday, answer disputes and remind the league about waivers. On Thursday, remind managers about early game locks. That routine is small, but it prevents most avoidable issues.
If nothing requires action, do not invent work. The commissioner checklist is about staying ahead of problems, not dominating the league chat.
Common mistake: letting small in-season tasks pile up until they become public disputes. A short weekly routine keeps the league calmer.
Weekly Risk Table
| Risk | Preventive check |
|---|---|
| Missed waiver deadline | Reminder before processing |
| Inactive manager | Lineup activity scan |
| Trade dispute | Respond within 24 hours |
| Playoff confusion | Publish standings and tiebreakers |
What To Escalate
Most weekly issues need only a reminder or quick clarification. Escalate only when competitive integrity is at risk: inactive managers, suspected collusion, platform scoring errors, unpaid dues affecting eligibility, or unclear rules that could change standings.
When escalation is needed, document the facts before deciding. A commissioner who can point to timestamps, screenshots, and written rules will be trusted even by managers who dislike the decision.
