He's not the only one that made mistakes. I still feel its a overall coaching issue. The elite level of execution isnt there, and thats all on the coaching. From the weak training camps, conservative plays, etc
The Bills should have never been in position they were in the final minutes of the fourth. I blame the defense for getting too conservative, especially against a team like the Pats. Saying that, coaching may have put them in the position to lose, McKelvin fumbling was the worst case scenario. He will take the blame, rightly so. I just dont agree with him getting all of it.
