I don't consider myself an out-and-out football expert, but I do like to read and understand as much as possible about the technical aspects of the game. One thing I don't believe the public is generally grasping in this debate is how technical the position of wide receiver is in the NFL. In college, the fastest players or most gifted athletes can dominate as receivers because they can simply outrun or outjump defensive backs for the ball.
In the NFL, successful receivers certainly have that ability, but their success is more predicated on superior technique and fundamental skills- route-running, getting out of their breaks at the correct times, body position and control, catching with the hands (as opposed to the body), making sight adjustments and choosing correct routes on multiple-route schemes, breaking off routes when appropriate, a profound understanding of coverages, non-verbal communication with the quarterback, etc, etc.
It seems to me that Devin Hester doesn't have any of those skills...he could take a screen pass or designed swing pass and try to make something happen in space, or he could just take off on a go route (or 9-route, in NFL parlance) and try to beat a corner in one-on-one coverage. But he'd lose almost any jump ball and he has questionable hands. I just don't see it.
