If the Bills had a competent QB, that ranked in the middle of the league in "deep pass" completions, I feel the Bills offense would be very successful under Gailey. With defenders spread out to prevent the deep pass, they wouldn't be crowding the line of scrimmage, which would be a huge advantage for the Bills run game. But since Fitz is the worst passer in the league in regards to passes thrown over 20 yards, defenses play the entire field as if it were the red zone against the Bills.
