I'm not sure who Miami waives to get Bynum. They'd love to get rid of Joel Anthony, but not enough to eat two years of his salary to pick up Bynum, and they're not going to get rid of Mason or Beasley. And I'm not sure if he's a complete game-changer with Miami. I think they're going to see if Oden can play.
But he could potentially be a game-changer for the Clippers. They're backup bigs are Antawn Jamison, Byron Mullens, and Ryan Hollins, and Blake Griffin can't play center. That means they're going to have to rely on DeAndre Jordan in crunch time, who I still don't totally trust in big playoff games. Bynum would be a nice insurance policy to have. I thought that person would be Emeka Okafor, but Phoenix is unexpectedly good, and I don't think they'll cut him now.
So, in short, I think the Clippers are more likely to sign Bynum than Miami.
