If AR stays upright it's a tough game to lose. I wouldn't worry about DAL playing D the way BUF did. They simply ain't got the horses to pull that off. Only a few teams in the league do: SEA, BUF, DET is iffy. BUF's secondary is head and shoulders above DAL.
IMHO I think too much credit went to Buffalo on that GB loss. Our star players had a bad game, while our o-line played well. I am not worried at all.
It's like the Bills players used some brilliant defensive tactics to cause a wide open Jordy to drop the ball.
