I think they are a top candidate to take on someone like Humphries. He would allow them to get to the salary floor, give them some depth, and not really compromise their tanking or their cap space for next year.
BTW, I LOVE what Philly is doing here. It is rare you have an opportunity like they have to truly bottom out and reload in such a short timeframe. They have a chance to go into 2014-2015 with up to 4 blue-chip prospects (Noel, Carter-Williams, their lottery pick, and NOH lottery pick), and a ton of cap space.
They fell into that deal with the Hornets, and it really presented them with a golden opportunity. In general, I am not a fan of tanking, but when an opportunity like that falls into your lap, you need to jump at it.
And the best part is next years free agent class will be loaded with really good veterans, that they can add to their young guys, and help them develop quickly and the right way.
