based on him identifying and coaching up QBs? He was the only one to recruit Mayfield..as a PWO player. Coached him as a starter his FRESHMAN season. He mentored Case Keenum, coached Webb (who's in the NFL), Bowman, and some loser that goes by JFF.
Kliff can identify, and coach players up.. He's an asshole to his QBs because he expects much more which rubbed Mayfield (go figure) and Webb wrong. But he's the goods.. Now as far as HC goes.. yeah he's not as good as Riley, although if he were let's say a coach at a blueblood who would have gotten a transition from an established coach, things would probably be different. He wouldn't have hired his under qualified homies off the jump in Lubbock.
