Fug'n Dennison. The references to him "Rex-ing up the offense" are spot on IMO. A good coach should adapt his scheme to the personnel and not try to pound his square peg into a round hole.
Is Miller a great Guard? No. But he's good at what he does and the Bills should take advantage of that (as well as Incognito's strength in pulling and man-on-man blocking).
Vlad the Impailed has great movement skills--the problem is, he's always moving in the opposite direction of the DL he's trying to block, resulting in way too many 'O le' plays....
