Pat Riley fired the first shot Tuesday in the Battle of Shaq's Bulge. The Heat coach wants Shaquille O'Neal to lose weight to aid his recovery from knee surgery.

"Right now I hope his thought process is that he tries to almost reinvent himself physically," Riley said. "Because this is the first time that he's really had something wrong with his knee to the extent that there's been surgery on it."

Riley said it's important that O'Neal "come back a lot lighter, a lot leaner."
