I think with Belichick, you can't confuse the POSITION with the PLAYER. I think for Belichick, the POSITION of running back is crucial, but he doesn't value any PLAYER in that position that highly, because he knows there are other ways to get what he wants. I personally think that Belichick makes fun of the organizations that drop tens of millions of dollars on guys like Le'vean Bell like we make fun of musicians that lip synch.
I don't know what to think about that Giants pick. Those are the qualities they value as an organization - tough, good positional mind - even if they haven't really shown that lately. I don't know. Proof will be in the pudding, I guess.
