The way this offense is run says more about the OL in pass protection than any stat.
1. We routinely pass the ball 30+ times a game.
2. We don't run max protect fronts to protect Manning. We'll keep a RB in there to block but you don't see us really going with 6+ blockers unless it's an overloaded blitz.
That says more about how the coaches feel the OL is performing because if the pass protection wasn't good enough then you'd see a lot more max protect fronts and not passing the ball as often with 5/7 step drops.
