I'm having a hard time understanding why they have smaller guys (often only 1 guy) pushing Allen. If you are committed to the play why aren't there 2 huge linemen pushing him?
Also if you watch the Eagles, who are by far the best at it, they stay low and immediately push straight forward. The Bills hesitate, don't stay low, and tend to go forward at an angle to the line; all of which makes the forward push less efficient. Just wondering why they don't study the Eagles and do it right.
