I am not, nor have I ever been, a Wells fan. I will give him credit for learning how to 'fall forward' in the preseason, but that is, in general, against backup/roster depth players, not starters. Wells was our starter in 2002 and was a 3rd round pick. DD was a 4th round pick and took the job away from Wells. And rightfully so, IMHO.
Wells will get credit for learning how to be a 'bruising RB' from me, when he does it, consistantly, against other starting D's. Until then, he still has alot to prove and EARN back. The guy has the build to be a punisher, yet he plays like a prima-donna, IMHO.
Watch most of the game tapes from last year, DD gets hit, doesn't go down till the second tackler gets there, and still manages to fall forward. Wells turns his back to the tackler about the same time that the tackler gets to him.
I think Wells being moved to FB is an indication of the team trying to find a roster spot for him, and basically admitting that he is NOT what we are looking for in an every down type RB, but he MIGHT be what we are looking for in short yardage situations as a decoy perhaps more than anything else.
