While I don't disagree that his tenure will probably end in failure or him leaving for a better/different job before achieving success at Colorado, you are very wrong about 2 different things.
#1, it is way way easier to be an authoritarian/disciplinarian coach with middle to upper class kids. Try doing that with kids who grew up with less father figures, more violence, and less structured high school coaching and you are not going to have a good time.
#2 and more importantly, power conference schools with any draw (which Prime Time brings to CU) don't need to recruit anyone from the local area if they don't want to. He could have a roster constructed from only deep south and LA kids if that's what he wants.
