Wells couldn't see the field for the Colts. If you can't block or catch the ball, you can't be a RB in the Colts system. It has nothing to do with talent level. I think we all agree that Wells is the more talented pure runner, but he would really hurt the Colts when he was on the field. If the Colts drafted Wells, the only time they could really use him would be as a goal line/3rd and 1 back, and you don't draft a RB in the first round for those two situations. I'll give you catching the ball. He's not going to be great in space (Brown isn't either) but Ohio State backs are never asked to catch the ball out of the backfield and usually end up being pretty good. Wells size/speed combo is better, gets downhill better, is better at the point of attack. As for blocking, I don't really buy that as something that's unique to the Colts. All NFL backs need to be able to block now if they want to be 3 down backs. If you don't believe he can block then you coach him up. The NFL is full of talented runners who weren't great pass protectors. Brown is kind of like Matte Forte version 0.7
