There's zero sense it adding Jamison other than "he went to college nearby". There's been enough adding of UNC/Duke guys simply because they're UNC/Duke guys as it is. Let him go to some playoff team with little to no depth.
I would love to have Jamison here. He would provide a much needed veteran presence and leadership and would be able to pick up some minutes at the back-up SF/PF positions. But more than anything, the leadership and mentoring aspect of what Jamison could provide is what makes me interested most. Unfortunately, I don't know if our roster can squeeze him in, but I would certainly love if it could.
The latest on Jamison is he is close to signing a one year contract with the Clippers.
The only way I could see Antwan coming back would be as a mentor for MKG at the 3 spot. He'd have to come cheap (vets minimum which he probably won't do) and without the assurance of ample playing time (which I'm not sure how he feels about). He can absolutely add value to the Bobcats and at the right price I'd be all in.
