I agree, Cubby. And I'm not super sold on Vince. A lot of people think he was an upgrade over Hedo, but I don't think so. It's all about fit, and I don't really think he fits this team.
But the reason I still think they're an elite team (and better than Boston) is because of their other acquisitions and the rest of their roster. Matt Barnes was a steal. Retaining Marcin Gortat, while pricey, is a great retention of talent. Brandon Bass is also a useful player. Plus their other guys like Dwight Howard and Rashard Lewis aren't going anywhere. So I think Vince's potential to damage the team is reduced.
I still think they look a lot better than a gimpy, aging Boston. I don't see any way that the Celtics are in the Finals come June. Part of it is because I'm not at all sold on their Rasheed Wallace pickup. He's getting too old and demands the ball a lot, and his outside shooting is shakier than it used to be. I just don't think Sheed is a get-you-over-the-hump kind of player any more.
As for Cleveland, I don't love the Shaq move, but I like a lot of their other moves such as grabbing Jamario Moon. And Shaq, for all his faults, will at least provide a big shield for Lebron, a cushion (made of flab). He'll deflect a lot of the pressure and make Lebron feel freer to do his thing. I think it will help, and that the Cavs will rush out to the #1 seed in the East by a wide margin.
