Off to a 4-5 start and without a win against a quality opponent, are the Boston Celtics still an elite team? Coach Doc Rivers believes so, even if he admits his team needs to prove it. "Well, we'll have to find that out. I think we are," he said after Thursday's practice at the Celtics Training Center at HealthPoint. "But, obviously, we're 4-5 right now. Our record says we're not [an elite team]; we say we are. I'm just going to warn you, it's nine games. Don't jump off the bridge yet. I can feel you jumping off. "What I'm saying is, it's early guys. Coaches always worry about their teams, that's my job -- concern [and] worry. That's what it should be. If we were 10-0, I'd be concerned that we're getting overconfident. We're 4-5 and really haven't beaten anyone yet. So we have to do that, eventually, if we want to be an elite team."
