The DL and DB rooms were deep enough to get them into the championship game. But you can watch the defense play against Indiana and Georgia, and then against Penn State and Ohio State, and in my opinion you can tell that they weren't as sharp as they were in the two earlier games. I also think that a few times against both Penn State and Ohio State, the youth of the LB's was still caused some mistakes that the opponent cashed in on. If the DL had been fully healthy with Botelho, Traore, Mills, and Cross, and the others could be depth to rest them, I think the QB has a lot more problems against the ND secondary, even without Morrison.
