I am thinking he would most likely bring back Lopez or Frye, which I wouldn't be horrified with since he may leave for nothing anyway. Gortat's value has never been higher. I would rather wait another year on him. Look what happened to guys like D. Wright, T. Evans, and C. Frye given another year after their career year. We would just have to give up too much.
But, yeah, I would definitely do the deal if Phx was up for it.
