How much cap space do they have left? Do they have a bunch of trade exceptions from dumping Asik/Lin?
Only way I could see it happening would be if it was Rondo + Wallace for a boatload of cap space, but even then it makes no sense, because all they seem to have as an asset is Terrence Jones... and he's only a slightly more valuable PF than Sully and Oly.
Maybe if it was a 3-teamer where Jones went to the Kings, McLemore, some bleh picks and tons of cap relief go to Boston, Wallace and Rondo go to the Rockets.
But I'm saying that without actually looking into Houston's current cap situation. I'm too lazy to look. Pretty sure they can't even absorb Rondo + Wallace .
