I have it listed that Bynum is costing the Cavs $12 million. The Lakers are way over the cap so the best they can sign him for is $5 million (and, probably under the new CBA rules, for the $3 million mini mid exception). Given this, the Cavs still have to eat $7-9 million of his contract and won't be able to get under the cap for probably another year.
I don't know. I guess it would depend on what the Lakers really are demanding, but they seem like they're going to be screwed by his salary for the next two years either way.
