Gasol is stuck in LA. No one wants his contract and at the same time they want LA to be a bottom feeder. LA has a huge TV contract, and other teams are feasting on it because of shared revenue. That won't change because of Pau Gasol. If it were threatened however, if there was a "win percentage" clause, you'd likely see other teams give up talent to LA just to keep the cash inflow, because that's the target for most franchises; ahead of winning, ahead of their own ticket sales... money from things they don't pay to support.
I could see Amare in Houston with Howard. I cannot imagine him in LA.
