I'm sure this was said somewhere in this thread, but this move is dangerous for more than just our chances to win - it sends a message to recruits and any of our current offensive players who may be on the fence about staying.
It sends a clear statement that Richt isn't interested in giving younger guys a REAL chance, even when it's obvious that the younger guy not only has the potential to be "the future," but also has a far higher ceiling than the incumbent.
It also lets recruits know that if you want to get noticed as a part of a productive offense, Miami isn't the place for you. We're raking in elite defensive recruits because who wouldn't want to play in the Diaz havoc scheme? But our offense? QBs, receivers, RBs, OL, etc aren't going to want to touch us with a 100 ft pole.
Perry should have finished out the game last week. The deficit wasn't huge. He led us back once, he could have done it again. Not only was his confidence destroyed by subbing in Rosier permanently, but now the message is being sent that as a young starter, you're on a short leash and we will replace you with someone half as talented solely due to seniority.
Nice one, Richt. Nice.
