The margin of error in most games is a td or less right? The the 3rd and 3 play where allen threw the ball down the sideline should not have even been an option. Pats throw it to welker across the middle and most of the time it's a first down. The play before allen and made a great throw to knox who made a great play himself. One more scoring drive per game and this team has close to a top ten scoring offense. Problem is they make these key mistakes when the numbers say in those situations to run a more high percentage play. That's the margin of error the Bills don't realize and Belichick has always realized.
