I don't have any numbers to back this up, but it's seemed to me that while Mario was an edge rusher in the 4-3 he preferred to go outside rather than inside. I can't remember him developing a strong inside move, a la Dwight Freeny. In the 3-4 Barwin, Anderson, Von Miller, or whoever will be coming off the edge. Does Mario have any inside moves to speak of? At his size, does he get low enough to get leverage? Will he dominate when he's in position to be blocked by G/T or C/G combinations? I know there were times that he fought through TE help and getting chipped by FBs, etc. but can he penetrate the way Phillips 3-4 is described?
