If I were the Kings mgmt I would remind Artest that he has a real bad reputation all over the NBA. He should go to the Kings, play hard and make nice for this season and the next, rebuild his trade value, and then the Kings will trade him, with his input, if he wants to leave in 2007.
Even Artest decides to leave in 2007 he should have a high trade value, supposing he rights himself. Artest gets a chance to wipe the slate (partially)
clean, a player friendly coach in RA, and the opportunity to have a say in where he will be traded to. OTOH, if he continues to be an f-up, no dice, your NBA career is toast, Ronny.
That's win-win, and it's got a kicker to keep Ronny straight.
