CC hasn't won a game at GW yet. He also hasn't lit the world on fire the last 2 months at GW in terms of recruiting. Lets wait a few years before we start worrying about others poaching our coach.
I would be ecstatic if CC leaves for Miami in 2 years - that means he would have saved this program from the dumpster fire of the last 6 years - but I'm not holding my breath.
