I really think Nash to the Mavs makes a lot of sense. He can get a ring, split time w/Kidd (who probably retires after this year) and the Mavs keep the cap space after this year to go chasing after Deron and Dwight. If Deron isn't interested then Dwight would still like to play w/Nash. ALSO, it keeps Orlando from getting him, which would maybe keep Dwight around.
However, the Mavs won't absorb an extra contract from Phoenix because of the cap space plan, I think that's why we'd be a great facilitator.
Odom, Felton to Phx
Beauboius, Frye to POR
Nash, CJohnson to Dallas
Beauboius would be great here w/Batum. Yes I know, he's not a true PG, and we have Jamal. However, I think Beaubious/Batum would be a terror on defense at 1/2 and their ballhandling together would make an adequate fit (at least in the second unit). Beauboius is probably a Crawford type of player, which is why it'd be good to also possibly have another trade for a PG, but I'm sure he'd offer more than Felton at this point.
Additionally, we could probably trade Crawford for a PG to finish out the season, or just play Nolan a bunch.
