You do realize that most of drafting is about fit right? Getting thrust into a situation with the best Coach/QB in the NFL is going to be great for almost any WR. Andy Reid has made a career out of running great offenses with subpar talent at WR.
And I'm not saying Worthy is a subpar talent, his speed obviously makes him a great threat. But could you imagine Worthy in a Mike McCarthy offense where he's running 7 yard curls most of the time? He'd be a MUCH less useful player here. Same with if Nabers/Odunze/Harrison JR were on the Chiefs, their #'s would look much different. Do you think Worthy would be having a good year on the Giants or Bears?
Coaching and fit almost matters more than anything, we've been seeing it with QB's who written off for dead because they were in bad spots but are now thriving.
