Mario Chalmers doesn't want you to believe in him. He doesn't want your support.

Some people thrive off of positive reinforcement. You know these people. You might be one of them. It's a natural human condition. Chalmers is the opposite of that.

Your doubts fuel his soul.

Chalmers' friends will tell you that he plays with a chip on his shoulder. It's more like a boulder. That's why, leading up to the Saturday's three-point contest at All-Star Weekend, Chalmers went searching for motivation from his teammates.

Even among his most trusted allies, Chalmers wanted someone to dismiss his chances of winning the exhibition.

Among other long-distance shooting luminaries competing at Amway Center, Chalmers is up against fellow teammate James Jones. Jones is the contest's reigning champion. Most of the Heat players remained predictably neutral when pushed by Chalmers to choose a side. Chris Bosh, for example, said he wanted both players to win.

But Udonis Haslem doesn't do neutrality. Haslem told Chalmers straight up and stone-faced that he's pulling for Jones, his boy from the 305. That's all the motivation Chalmers needed.

"That's just me," Chalmers said. "Coming into the NBA, I felt like I slipped in the draft and a lot of people overlooked me. I just want to go out there and prove people wrong."

You know, like those people who said before the season that the Heat still needed a solid point guard to complete its roster.

Pushed by rookie Norris Cole, playing healthy for the first time in two years and trusted, finally, as the team's starting point guard, Chalmers entered the All-Star break leading the Heat in three-point shots (68). That's more than the combined three-point total for Mike Miller (30) and Shane Battier (61).
