yes, but perhaps there are too many voices which can be distracting and impacts the game plan. take the seattle game for instance, where was the plan to test their secondary filled with street free agents picked up that week. there is a reason other teams in the NFL dont have 4 people calling plays. to me this is another way of BP "spreading the blame" in case things dont go well.
our game plans seem to be too conservative both on offense and defense. take NO for instance, their defense is good not great, they understand that and their offense does not let up and goes for the jugular every chance it gets, this ensures that if the defense gives up a few plays late, it does not cost them the game. we seem to labor under the false impression that our defense is great and we play everything close to the vest and end up losing close games late.
