It started last year in camp. Gruden pretty much said that you can't touch Pryor. He was off limits to hits and what not. Pryor knowing this started making one handed catches and running his mouth. The defense was not allowed to bump him, tackle him or hit him.
He took advantage of that and started to show the defense up. DJ and the D didn't take kindly to that. That's why DJ said this year, "Gruden can't save you."
