Yea that's a lot of the speculation. His contract is only guaranteed for $6MM of the $12MM this year, but there is a cutoff date of Jan 7th. He could be trying to get the Cavs to cut him before Jan 7th, as they would to save $6MM to get a cancer off their team, to force his way onto a winning team. He's playing this perfectly, if that's his angle.
Lots of people out there saying Bynum really doesn't like basketball and that a lot of executives had big concerns about the way he went through his rehab.
Cavs want to trade him, but teams may prefer ot wait until he's waived, knowing he's prone to not trying if he's not on the team he wants to be on, which is apparently the Heat and Clips. If I'm a team with legitimate championship hopes, I wouldn't want that kind of player around.
I really don't think this may be the trade answer for Asik. If Rockets aren't the team he wants to play for, it wouldn't make sense. And if it is a team he'd want to play for, why not just sign him after he gets waived.
