This isn't just a GT - CGC clearing the roster of CPJ's guys thing, this is becoming quite normal in college sports now. Just look at what's going on in the basketball side of the this site. Wait until the one free transfer rule comes into effect...it's going to be even crazier.
Going forward, I expect CGC to recruit the best SAs he can, and I expect the roster to take of itself in practice and game days. I would not be surprised to see even MORE turnover in the future among the guys CGC brings in. If you recruit elite guys, they want to play...if they don't they leave to try their luck elsewhere. It's like that anywhere now.
