‘Marv Levy sent Sean McDermott a congratulatory email after the game. Fitting, since McDermott is the best coach the Bills have had since Levy – by a mile. All week, and all season really, the Bills have been focused on the task at hand. Even with a long-sought-after division title looming, McDermott wouldn’t allow his team to look ahead. That’s good coaching. It wasn’t a perfect Saturday. The offensive penalties in the red zone were maddening – and just might get the Bills beat against a better opponent. McDermott’s challenge was ill-advised. The defense was surprised by a third-and-8 run play by Denver that went for a touchdown. While it wasn’t perfect, it was more than good enough. The Bills are for real, and it starts with their head coach.’
