I expect that the Sixers would ask for a star price for Noel.
I don't see Noel as a star player, or even an elite one way player, given his injury concerns and the fact that he's not a dominant rebounder.
He's a nice role player. A big man version of Marcus Smart, in a way, as a prospect.
It'd be nice to add Noel, but in my opinion not worth trading a top pick or a nice prospect and a bunch of lesser picks.
