ND had a stout front 7, not as athletic at LB and safety. Didn't have a great edge rusher. This year's team is quicker in the front 7. They get into the other team's backfield regularly. And the safeties are better overall. Add Julian Okwara as a pass rusher, replace Fox with Coney at LB, and swap out Motta with Gilman . . . ND would have had spectacular D in 2012.
