 NFL background as a coach. He spent some time with the Ravens and some other teams. What he did at UCLA last year, their schedule was easy, but very, very impressive. That was not a good defense, and he came in and made them a really, really talented defense, so that's something to watch for sure. The big change, though, is last year UCLA had Liatulatu, who was, I think, either the first or second defensive player picked in the NFL draft, a great defensive end. USC has no one even close to him on the edge, so that's going to be a little bit different
