The Bills capitalize on Spiller's explosive speed and acceleration by frequently running off-tackle plays when he is in the game. One of their favorite plays is the outside zone, which instructs the runner to aim for the outside leg of the offensive tackle before making a decision to bounce (runner takes the ball around the corner), bend (runner cuts the ball back against an overaggressive defense) or bang (runner attacks the open crease with the intention of gaining at least four yards). The offensive line steps in unison to the direction of the call, with blockers assigned to take the first defender that shows up in their area. Based on the defensive front, either the center and guard or the guard and tackle will execute a double-team block to neutralize penetration at the point of attack and provide the runner with a clean look at the hole.
