Debatable. I don't rate Bynum @ all, and Odom, while a very good and solid player, tends to blow hot and cold. He is the epitome of inconsistency. Gasol and Artest, I can't argue with. Both extremely talented players who understand their roles very well.
As for the Celtics, well, I do agree the addition of Wallace is huge, but the guy is on the wrong side of 30! Garnett has recovered, but is he back to the same level of 2 seasons ago? It remains to be seen. As for Pierce, I hate the guy, but he is a very good player, although not as good as he thinks he is. Perkins is a solid player, but I still think he in inferior to the likes of Howard and Gortat. Too many ifs and buts here.
The Magic have youth on their side, as all these guys, bar Lewis, are 25 or younger.
