Unlike discovering “sleeper” running backs, there is more logic in trying to identify wide receiver talent. Carries are mostly distributed in a linear fashion and inefficient players can continue to receives because teams just run the ball; they refuse to think of the run-pass dichotomy in a different way. However, on any given pass play, there are four or five eligible pass catchers running routes and the best wide receivers/tight ends/running backs will earn a disproportionate amount of a teams’ targets.
This is because targets are an indicator of skill. Better players are open more often, or at least able to create situations in which quarterbacks feel comfortable throwing at the said player.
