Dwyane Wade is coming off a gold medal victory this summer but still believes he has something to prove after the former NBA Champion Heat struggled last season.

"My team was 15-67 last year," Wade said. "Of course, I'm going to always have fun and enjoy the game, but at the same time you have to play with a chip on your shoulder. And I feel everyone in the locker room should play with a chip on their shoulder, because we have something to prove."

Wade admitted that playing against the world's best in Beijing helped restore his confidence.

"It was more important than anyone knows, just for your overall confidence," Wade said. "Once I got there (to Beijing) and started playing against, and with, the best players in the world and succeeding, it makes you understand and know that, OK, I'm back."

Making the playoffs won't be easy for the Heat, but stars like Wade, Shawn Marion, and rookie Michael Beasley should make Miami competitive.

"Once you see that something is done, it makes it easier for you to have the vision that it can be done again," Wade said. "Of course, they did it unbelievably, not only did they have a quick turnaround, they won a championship. I think after the season we had last year, we won 15 games, it's not going to be difficult to have a quick turnaround."
