Myself personally Shaw, the D has played fairly well , but in this league without an Offense that can control the clock to keep the oppositions high powered O off the field or match the intensity/ points scored its all for not. QB's like A Luck are going to put you into a shoot out.
On the other hand when you look at the cards Daboll has been dealt at the QP position in Peterman, the rookie Allen, now a rusty, perhaps over the hill veteran in Anderson is easy to understand why the O has struggled as a unit in my humble opinion.
The Bills GM worries me.
