I think for Philly to trade both Okafor and Noel, they would need the BKN 2018 in addition to Jerebko and Rozier and even that might not be enough. I think this is easier to digest if you keep SAC out of it. Philly is trading Okafor and Noel for Jerebko, Rozier, and BKN 2018. So if you can get Philly to bite on that part, then just swap Okafor for Len and call it a day (PHO would probably do that).
It is not a bad trade for us, I am not a big fan of Knight (or his contract) but Len and Noel are decent players. I don't feel as though it moves the needle enough for us though. We are still a mediocre team after giving up two pretty nice assets (at a minimum) for two different pretty nice assets in the trade. I would not be unhappy with the trade (my version of it anyway) but it also wouldn't get me all that excited.
