If you can be sure of getting Chris Paul circa 08-09 where he racked up 22.8 pts, 11 asts, 5.5 rebs, 2.8 steals per game and shot 50% from the floor, you don't even blink at taking on Okafor.
If you're going to get Paul from this past season where he averaged 15.8 pts, 9.8 asts, 4.1 rebs, 2.4 steals and shot 46% from the floor, I'm not sure you trade Rondo, Green and the Clippers pick straight up for him.
