Chris Andersen estimates he's at about 75 percent basketball conditioning but hopes to use the next couple weeks to regain top game shape.

"It’s a different game once you get out here and get five-on-five,” Andersen said. “That’s a whole different world of conditioning.”

To aid the process, Andersen -- who signed a 10-day contract with the Miami Heat on Sunday -- will go through two-a-day workouts.

“He has a lean, live body, so I think in the next three or four weeks you’ll see that change even more," Erik Spoelstra said. "He’ll get in better shape as the weeks go by. We have plenty of time left in the season."
