I totally understand the OP's point...
But Hackett's point would likely be that he envisions a Bills Offense as efficient as those Brady led NE Offenses...An Offense that, given an extra possession or two, will use them like a daggers against you...
That being said I'm hoping for some flexibility on the plan...Truth is though...slow or not...too many 3 and outs is going to lead to a bad season regardless...It's just a slower death if you slow it down...
