Rajon Rondo doesn't agree with those that are already expecting the Heat to win the 2011 NBA championship.

"They should be good, but they ain't done nothing yet," Rondo said recently. "They ain't done nothing.

"What is there to be nervous for?" he said. "I'm worried about L.A. That's the team we need to beat. Miami looks really good on paper, and I'm sure they're going to be really good. But they still have to come together as a team. I'm not saying they won't, but who knows if those guys can jell?

"Our biggest opponent each night is ourselves ? that's how I look at it. Not to be cocky or anything, but that's how we honestly feel. We are the defending [Eastern] champs. Once the first game of the regular season starts, that's irrelevant. But we are going to go into training camp looking to get back to the Finals and win it."

Rondo says it will all depend on how quickly Miami's three superstars are able to gel.

"It depends on those three guys [James, Wade and Bosh] in particular, how they accept their roles," Rondo said. "Things aren't going to go each guy's particular way. It's going to be about how they handle it as gentlemen."
