you're being disengenuous here and you know it. He used it until it mattered and then he didn't. With the lack of parity that existed during the vast majority of his tenure, very few of his coaching decisions mattered. In big games, they did matter and he lost way more than he should have. He moved away from his blue team every time it mattered later in his career, because even he decided it was silly.
I'm not being the least bit disingenuous. If you two think he quit using the blue team, you're both totally clueless about Carolina basketball, which doesn't really surprise me. Since you're not Carolina fans, you have no reason to be extremely knowledgeable about it. Just don't act like you do have a clue regarding it when you clearly don't.
