This is a HUGE upgrade for the Spurs. The Spurs will miss Barry in the area of depth but Thomas is a MAJOR upgrade from Fabs. He is a better defender in the post, a more consistent 18' shooter and a better rebounder. He will help the Spurs a great deal.
I can't agree with your assessment of Damon Stoudamire, Lurker, not too many people were interested in the guy -- he is a streaky, inconsistent shooter and a poor defender. I don't think he is much help to the Spurs.
I would also agree with your assessment on the rankings of the better trade deals (that's scary!):
Lakers - Gasol steal, Ariza solid deal for little used Cook.
Spurs - Stoudemire pickup, Thomas for 2 players who are out of the rotation.
Jazz - Korver
Mavs - Kidd cost more from the rotation than the others; not sure he will upgrade the offense as much as he will hurt the defense
Suns - traded on-court energy for lockerroom harmony; will be the most interesting one to watch
I'm not sure why the Jazz's signing of Korver isn't receiving more attention. I think this trade was FAR better than the ones that are considered "blockbuster" trades (i.e. Mavs and Suns). I think that the Mavs gave up far too much (esp. in the interior) to get Kidd. And I think the combination of losing Harris and Diop is more of a subtraction than adding Kidd to the roster. Have the Mavs forgotten that Diop has been their only interior defense in the past playoffs? Dampier is not only inconsistent but simply disappears at times.
I still say that the Suns lost far far more than they gained in adding Shaq. I STILL believe that Marion was the best Sun all-around player. No, he wasn't the leader but he was their BEST defender, their best finisher and it could be argued their best shooter (although I would give Nash the nod in this area).
IMO, the Mavs and the Suns got worse, not better!
Congrats to the Spurs -- the playoffs this year are going to be GREAT!!! (hopefully, everyone [esp. the Lakers] will be healthy)
