I just can not fathom any scenario in which KG would even consider the Nets.
In my estimation, KG will do one of three things. Re-sign with the C's, go back to Minny, or retire.
I honestly could see him going back to Minny. They have a good young team, a rebounding machine at PF, and he still has a warm spot in his heart for that franchise. If KG thought by going back, Minny would become a legit contender, I could see him seriously considering it.
I just don't see him trying to latch on to a contender as a spare part to get a ring. Doesn't seem like his style.
