Crap can him? WTF are you blathering about? Pull your panties out and quit reading things that aren't there.
No one is disputing the overall talent of the WR corps but you are clueless if you think that they are a fast bunch. It is a critical element of the offense for them to be quick on intermediate routes and over the middle because the o-line isn't generally capable of protecting long enough to actually stretch the field.
If they aren't capable of creating some kind of separation in these areas, like Bolding didn't on that play, the offense is gong to come to a screeching halt like it has against SF, Indy, etc. Green Bay has a really good secondary so the passing game is going to have to take advantage of matchups in other areas and if Boldin can be shut down by a LB in man coverage Arizona's season will likely be over.
There WR's and their overall production prove that they get all the separation they need. Really hard to argue otherwise.
