This might make sense, Arenas is hurt and out till Feb. Plus he is not happy in Washington and is going to opt out most likely right? JO would give them a real PF, and the Pacers would let Arenas walk (or try to sign him, God, I would love to have a prolific scoring SG on the team) The Pacers would instantly be out of cap probs and be able to sign all the young talent we have and will have.
anyway, I just pulled this one out of my butt. I didn't do any fancy Real GM legwork or anything. It just seemed like an interesting trade idea.
