He has come out of some great programs and he's been on some great defenses. He was at Alabama four years ago when they were No. 1 in the nation (defensively). He coached the secondary there. And he has great experience. He's been doing it the right way for a long time.
The quarterback part, to me, is secondary to him as a person. His background, being from West Texas, tough, unselfish, not spoiled ... he's a can't-miss guy, in my opinion.
