Fantasy Analytics
Target Share, Snap Share, and Role
5 min read
TL;DR
Fantasy points are volatile week to week; role is not. Snap share and target share tell you what a player is being asked to do, which predicts future production far better than past production does.
Production is noisy, role is stable
A receiver's weekly fantasy score bounces enormously — one long touchdown can double it. His snap share and target share barely move from week to week, because they reflect a coaching decision rather than a bounce of the ball.
That stability is exactly what makes them useful. When you want to know what happens next, look at the thing that does not jump around.
The three role measures
- Snap share — the percentage of offensive plays he was on the field for. The broadest signal: you cannot produce from the sideline.
- Target share — the percentage of the team's targets he received. Narrows snap share down to actual involvement in the passing game.
- Route participation — how often he ran a route when the team dropped back. Separates a receiver who is on the field blocking from one who is genuinely in the pattern.
Read them in that order. A rising snap share with flat targets is a player getting on the field without being used.
Where the signal turns up first
Role changes show up in these numbers before they show up in fantasy points, usually by a week or two. A back whose snap share jumps from 35% to 60% has already been promoted; his points will follow once the touchdown variance evens out.
This is the practical case for watching usage on our NFL Usage page rather than the scoring leaderboard: the leaderboard tells you what happened, and usage tells you what the coaching staff has decided.
Keep these
- Role metrics are stable week to week; fantasy points are not
- Read snap share, then target share, then route participation
- Usage changes appear a week or two before scoring changes
