Not that it matters, but here's what I think. I think HCPN actually is, maybe was, a defensive guru. You cannot deny the schemes and performance of his D when he was at MSU. I also remember listening to him when he was one of the crew for the national champ games. Dude not only knows so much about the game, but articulated it in a way someone who knows very little could understand. Which should translate into being a great coach. Hell, he would call out a play before it happened just based on how an offense was lines up. What I think the biggest problem is, well 2 biggest problems he has is 1) offenses have changed and 2) aside from Ga Tech, offenses just don't grind it out in the ACC. He's still coaching like it's 10 years ago when those things worked. Defense in general these days is way down and offense is way up. It reminds me of when the spread first came out...not sure it was really WVU, but that's not the point. Point is, D Coord figured out better ways to scheme, different personnel, etc and everyone copied it. Sooner or later someone will figure it out and the D will catch back up to the O.
Back to his 2nd biggest weakness - updating his style. Not so sure he'll do it. He's gonna need someone to have a long conversation with him about adjusting what his "base defense" is. I think he really is a great X and O guy. I really do. I just hope the X and O he knows or knew isn't antiquated and he learns to adapt
