Start/Sit Decisions: A Simple Process That Actually Works

Start/sit decisions come down to three inputs: usage, matchup and health. Usage is the strongest predictor. A player with a stable role, such as a receiver who sees eight targets a game or a running back who handles fifteen carries, is safer than a boom-or-bust option with a big ceiling but few snaps.

Matchup comes next. Defenses that allow yards and points to a position are targets, while strong secondaries and run defenses are fades. Use defensive rankings by position and, more importantly, the underlying numbers behind them, because early-season rankings are noisy. Weather and venue matter for kickers and passing attacks: wind and rain can sink a deep-threat receiver and boost a run-heavy game script.

Health is the tiebreaker. A questionable player in a late game is a trap, because if he does not go you have no replacement. When in doubt, start the player who is fully healthy and has a guaranteed role, even if his ceiling is lower. Avoid overreacting to one big game or one dud, and trust season-long trends over single-week noise.
