Based on the way we ran the ball last season, I actually would like signing Dillon better than re-signing Pollard. (Note: I was for signing a better version of Dillon such as Henry but knew that we wouldn't.) The scheme we used last year focused on runs between the tackles. If we're going to do that, we need a pounder not a player who is dangerous in space like Pollard.
I don't consider Dillon to be a better player than Pollard, but just a better fit. If he's not the RB we sign because of asking price, I think it will be one of the other bigger RBs available and then we will try to draft someone with more home-run ability to complement him (probably in the fourth round or later, although I hope it will be the second or third).
