I think he is but he's kind of caught, he doesn't have "his" players yet. BV is a front 7 guy and he needs those really good to great Dlinemen, we have decent Dlinemen but nothing really good, we do have depth and that's helped. A typical Great VB defense has at least one great Dlinemen and one great DE, with good solid mixed in. He will always have at least one very good LB. His DB's will play aggressive and that gets him in trouble, every once in awhile but not as much when he was at Clemson. The Cheetah, is the 2nd most important guy on the field for BV and injuries have really show just how much, that position means to a great BV defense.
So now he has to hype average players and try and get the best out of them. We have some really talented young DB's and that will keep going. The best DB in the world, will lose coverage if the QB has all day. And not being able to count on the cheetah, to spy a mobile QB or waste Stutsman, when he gets the call.
If BV gets some of aTm Dlinemen in the portal, watch how much his defense improves. It all starts upfront and BV will get the guys, he just hasn't got them on campus...................yet.
