Routes run take into account how a player is used when on the field, specifically for passing situations. While this is especially useful for tight ends (as they often split snaps between blocking and running routes), it is also quite useful for wide receivers.
This tool takes routes a step deeper and measures the rate at which a player is targeted on his routes and the percentage of his team’s dropbacks in which he’s running a route. You’ll be able to view a specific team so that you can compare players within their team’s situation. Also included in this is a lens into each players’ air yards share (which is listed in parentheses next to the player’s name). If you want a weekly breakdown of these stats (and more), I highly recommend subscribing to the Ship Chasing YouTube account and watching Pat Kerrane‘s Stat Chasing episode, which is published every Tuesday during the NFL season.
