This, in my opinion, is part of what's wrong with the offense this season
First, the Bills need to run Allen a few times earlier on. Defenses are now convinced that he's been coached to stay in the pocket more this season to preserve him for the long haul. Rightfully so, because the Bills have done just that this season. Hardly any designed QB runs! While I don't think he should revert back to doing this as often as he did in the past, I do believe sprinkling this in a little more this season will force Defenses to account for it. That's the plus to having Allen that has taxed D's the past few years. Use his running threat to set the rest up. This new plan is also getting him hit more than what he was when he was attacking the D with his legs. He's getting killed out there! He needs to be the hammer, not the nail
Second, what's this plan to not throw to Knox? Plays now are largely designed to use him more as a blocker or decoy. Josh loved throwing to this guy in the past. Why is it removed from the game plan now? Get this guy involved. You paid him, use him.
3rd, Cook is a weapon. I see them going away from him in favorable situations after he has gouged the D for 5-7 yards a pop. Mind boggling. He's the mismatch you need as an offense.
One last thing.... I've noticed in these last 2 losses, that the presnap motion is not being used much at all.
