I don't see Phil rushing back to the Lakers, they're salary cap situation and the bad rep Kobe has acquired will make it difficult for them to attract enough talent to make Phil want to come back.
He'd be more likely to reunite with Shaq in Miami or head to another team that's getting ready for an immenent run, that is his MO after all. And, I don't mean a team like Philly or Washington, that has potential. I mean a team that's got the pieces and is ready to take it all, maybe Houston or Dallas.
