NFL With or Without You (WOWY)

NFL with or without you analysis

How a team performs with a given player on the field compared to without him, built on snap participation data. Pick a player and see what changes for the rest of the offence when he is not out there.

What WOWY is good at and where it misleads

The question WOWY answers well is who absorbs the work. When a starting receiver misses time, the targets go somewhere, and this shows exactly where rather than requiring you to guess from a depth chart. That is the most reliable use of it.

The trap is treating the difference as the player's value. Games missed are not random. Players sit out for injury, for blowouts, and late in seasons that are already decided, and all three of those change the sample in ways that have nothing to do with the player. A quarterback who missed three games against the softest defences on the schedule will look less important than he is.

Sample size is the other constraint. Most players have very few games missed, and a four-game without sample is not enough to conclude anything. Treat small splits as a question to investigate rather than an answer.

Practical uses

The best time to use WOWY is the moment an injury is announced. It tells you which teammates have historically gained the most in that exact scenario, which is a faster and more grounded read than waiting for beat reporting.

It also helps price a returning player. If an offence functioned nearly as well without someone, the market often overreacts to his return, and the players who filled in are usually the better value.
