Okafor doesn't fit this team, so I wouldn't even entertain a deal at this point. Philly shot themselves in the foot in draft night, now that we have Horford that ship has sailed.
Say what you want about Smart, but he fits our core and is one of the top 5 best defenders in the league. I'd keep him around b/c he's proven a difference maker in big games. That kind of contribution is hard to replace. Should be improve his shooting, we will all be pleased Danny kept him.
Noel, different story. I'd offer Rozier and a raft of non-BKL picks. Terry is legit, would kill it in a starting role for Philly.
