Really, you dont know why Mundy sucks? Let me recap:
Thomas, broncos, schooled him for a TD 2x
He wiffed on tackling the raiders RB who ran for the TD (soory to tired to think if his name this early)
He wiffed in the tackle on mccoy on the first fourth down when he had dead to rights in the backfield
He totally missed his assignment on the punt block
If there is a bug play against our Def, he was probably involved! Get rid of him!
