Dwight Howard To Become Free Agent: Magic Center Says No To Contract Extension

Dwight Howard has a clear message for the Orlando Magic: win, or risk losing the all-star center.

The three-time Defensive Player of the Year said he would not sign an extension with the Orlando Magic this summer, and instead would become a free agent in 2012.

He said he would prefer to stay in Orlando, but that could change if the Magic don't win a championship next season.

"I want to win a championship," Howard told "I think the owners have to really know that. That's been my goal and my mission since I've been in the NBA -- to win a championship. I don't have side goals or agendas. My main goal is to win a championship. I want to have 14 other guys who feel the same way."

Howard hinted that the current Magic roster lacks players who give maximum effort.

"Sometimes guys are there whole-heartedly and then sometimes I've had teammates allow people getting in their ears and things like that effect the way that they play and approach the game," he said.

Howard has bristled at talk of his free agency. He accused the Orland Sentinel of trying to push him out of Orlando with "dumb articles" speculating about his future.

The Magic were upset by the Hawks in the first round of this year's playoffs.
