No wasn't hindered by the way he was used b.c before he was injured he was used that way in Wade Phillips defense and had 5+ sacks in the beginning of the season. He was used in a way where if everyone does their job the defense works, Mario decided to be a little girl and just gave up on even trying.
I know WAtt would never do that, he would try his hardest at whatever position he is put in on the field...
