I am not totally sure about all of the monetary issues, but more about the players involved. I will also explain potential reasoning for each team.
If Orlando really thinks Dwight is going, then this is the trade I would give to them.
Hear me out on this one. The Magic would want this since it gives them a starting PF and Center to go along with their wing players and Jameer at the point. While we would lose 2 of our starting lineup and 2 key bench players, Ryan Anderson or Brandon Bass could easily replace Odom as a good PF off the bench, Dwight is Superman, and Earl Clark could be a really good player in the league if given consistent minutes. This is risky, but I would do this as either GM.
DJ Augustin for Shannon Brown and Matt Barnes.
We finally get a decent young PG, and the Bobcats get two players that could probably start for them, especially after they dump Jackson. But why dump Augustin? They are in that horrible range of just missing the playoffs while not getting any good draft picks, and getting rid of Augustin allows them to tank even further. A 2nd rounder could be thrown in if necessary.
Chris Johnson is a blocking machine who is only 23, and if he adds weight and gets PT, could be a very good defensive center. Nicholas Batum would give us a young starting SF who can hit the 3-ball and plays excellent D. Wesley Matthews would be a great scorer off the bench who also plays great defense, and in a few years, if he progresses sufficiently, could take the starting job from Kobe. The Blazers finally get a Center to replace Camby and allow LaMarcus Aldridge to play his natural PF position, while Shannon Brown gives them scoring off the bench and energy, and Blake is a good backup for Andre Miller.
Critique away. I really would like to see some responses, since I think these are all fairly reasonable trades.
