it didn't say much you don't already know. they're gonna use him as a slot in hopes that he can produce like Welker. Then he'll be used as a change of pace #3 RB and that he'll even line up in the "wildcat" some.
Outside of ESPN, I've also read that an "unnamed" player has opened his big trap about a few completely foreign offensive packages based around McCluster.
So, there's little doubt Weis and Haley have been in the lab conjuring up some new offensive schemes.
