Here's the thing, the Lakers probably don't need Artest to win a championship if Bynum comes back healthy. But with Artest, they could be a super dynasty (assuming Ron Ron stays sane). Seriously, they could be winning championship after championship, for as long as Kobe can still play.
So there's no reason to simply give LA that final piece. I'm not against trading with the "enemy" but the Lakers are lowballing us. It's all in the eyes of the beholder, maybe the other 28 teams see Artest as a plague, but to the Lakers, Ron Ron may as well be Jesus Christ the Savior combines with Santa Claus.
Taking K9 from us for Odom is the least they should do. How much would you give up for the final piece of a multi-championships team? You'd probably give up all the moveable piece if that's what it takes, wouldn't you? So with that in mind, I'd counter with Artest + SAR + K9 for Odom + Farmar + Ariza + two future 1st.
That's a one-sided trade, I know. But if the Lakers don't have the balls to pull it, they don't deserve to be a dynasty. And if they walk away, well, that's just fine with me.
