Does the Artest deal help the C's?

Interesting theory explained on The CMSB.  Here's one of the 4 reasons:

How bad does Sheed look if he signs with another team for more money? Currently it sounds like the Spurs, Mavs, and Magic are in play (hat tip to Gary Tanguay's Twitter page). If he signs with San Antonio, it looks alright. If he signs with the other two for more money (or slightly more money), it looks like a money grab. If crazy Ron didn't go for the bigger pile of cash, why would 'Sheed? Also, he has played with Vince Carter before in college, do you really think he wants to do that again?

Interesting thought. 

Also interesting is the open letter to Danny Ainge on LOSCY regarding Leon Powe

What is so risky about this? If you were willing to keep on Sam Cassell and Patrick O’Bryant at the start of the season, why not keep Leon? Get rid of Gabe Pruitt and give his roster spot to Leon.

There is nothing that risky about this at all. For $800,000 you take a chance on a guy that helped you win the franchise’s 17th championship and would resign for the future TO BE your bench. He wants to be in Boston and Boston wants him here.

And you know, Danny, you know that Leon would have taken your 1-year contract at the league minimum.

He speaks for a large segment of Celtics fans.  Leon was certainly loved here.  I hope he knows that.  Maybe they'll find a way to bring him back
