Commissioner Dead Money Rules: How to Handle Dead Money and Salary Cap Rules in Fantasy Football
How to structure dead money rules in your league: the most common dead money frameworks are: (1) full dead money — the entire remaining salary of a traded or dropped player counts against the releasing team’s cap for the year the player is traded or dropped; (2) prorated dead money — the dead money charge is split evenly across the remaining contract years; and (3) cap percentile dead money — a percentage (typically 50%) of the remaining salary becomes dead money. Full dead money is most punishing and most realistic; prorated dead money spreads the pain; cap percentile dead money softens the penalty for signers who make mistakes.
Dead Money Rules Quick Reference
| Dead money structure | Commissioner use case | Trade market effect | Mistake to avoid |
|---|---|---|---|
| Full dead money (100% of remaining salary) | Most realistic; mirrors NFL cap structure | Discourages large, risky contracts; slows trade market | Using full dead money in a casual league — too complex; kills trade activity among newer players |
| Prorated dead money (spread across remaining years) | Balanced approach for competitive leagues | Moderate deterrent; managers can absorb one bad deal | Applying prorated dead money without documenting it clearly — ambiguity generates disputes |
| 50% dead money (half the remaining salary) | Best for leagues transitioning to salary cap | Softens the penalty; managers still feel the sting without being frozen by it | Setting too low a percentage (under 25%) — the penalty has no behavioral effect |
| Dead money triggers: trade only vs. trade + drop | Apply to both to prevent “drop instead of trade” workarounds | Consistent cap pressure regardless of how the player leaves | Trade-only dead money — managers will drop players they should trade to avoid the cap hit |
| Minimum contract threshold for dead money | Only apply to contracts above $10+ (or equivalent) per year | Frees managers to sign low-cost speculative players without fear | Applying dead money to all contracts — frees managers won’t sign low-cost backups and depth players |
| Dead money dispute (manager claims rule didn’t apply) | Reference the constitution’s exact language; rule on ambiguity by spirit | Document the ruling; clarify the constitution before next season | Retroactively exempting a manager from dead money — consistency is the only protection against future disputes |
Commissioner Decisions Around Dead Money
When dead money rules are triggered. Commissioners must define exactly when dead money triggers — specifically, whether dead money applies only to trades (a player leaves via trade), only to drops (a player is cut to the waiver wire), or both. Most salary cap leagues apply dead money rules to both trades and drops to prevent managers from gaming the system by dropping a player to waivers instead of trading them (to avoid the dead money charge). The commissioner must also decide whether dead money applies to all contracts or only to contracts above a certain annual value.
Managing dead money disputes. When managers dispute a dead money charge — claiming they did not know the rule applied or that the calculation was made incorrectly — the commissioner should refer to the league constitution’s exact language. If the constitution is ambiguous on the specific dispute, the commissioner should rule in a way that is consistent with the spirit of the dead money rule (penalizing roster churn) and note that the ambiguous language will be clarified in the next offseason rules update.
Setting Dead Money Rates Appropriately
Calibrating dead money to league activity. Dead money rates that are too high discourage all trading (managers become so afraid of dead cap charges that they refuse to make moves that would improve both teams). Dead money rates that are too low have no behavioral effect (the charge is so small that managers ignore it). A well-calibrated dead money rate creates a genuine trade-off: managers think carefully before signing players to large contracts because they know that trading away a player with a large deal will result in a meaningful cap hit, without making the penalty so severe that it freezes the trade market entirely.
