While the performance of the offense this year has been horrific often, I'd be surprised if Pegula blows it all up considering that the Bills have their best record in ten years. There have been some losses which really sting (ie Kansas City, Miami, Oakland, Denver), in which Marrone declined to go for 4th and 1s late. That's one part of Marrone's in game management which I question, but the Bills have also pulled out some of their best wins in a long time this season too. I'd say Marrone gets at least one more season as head coach, to see if he can get to 10 or more wins next year.
