I agree that Daboll had a bad game, but it was because they WERE NOT running the offense from last season. He changed it up and it felt like he was trying to prove what a genius he is..
or based on statements from the offseason that he outsmarted himself. He talked a lot about how you have to change or other teams will pick up on it and stop it. That's true, but he made some critical errors in his scheme. Teams learned the Bills won't try to run and if they do, it will be largely ineffective. Like mind boggingly ineffective. So they just sit 7 guys back in coverage.
The Steelers line is one of the best in the league, but Daboll should have put a lot more focus on the run game as it's the easiest way to make a team pay for sitting so many guys back in coverage. Instead, he outsmarted himself with his brilliant 5 wide formation.
