Interesting. If I'm Orlando, I want Hinrich as part of this as well though.
Something like Arenas, Hinrich, and Blatche for Carter and Lewis makes some sense for both teams.
For Washington, they get salary relief, as well as some talented players to put around Wall. And for Orlando, they take a swing for the fences with Arenas and Blatche, while also adding an excellent role player in Hinrich.
I actually think Blatche would be a very good compliment to Howard up front, and you can slide Arenas into the starting SG spot, and have Hinrich as the 3rd guard coming off the bench.
