‘Coaching the Bills means craving adversity. You have to be willing to school a young team all week until you see signs of improvement. Then, once progress is at hand, it’s time to sit down and devise ways to heighten the challenge by undermining their effort. Which is why the Bills are no worse than 4-1 on preparation, a scant 2-3 on game day. To coach the Bills is to see the enemy on Sunday and fail to realize it’s you.’
