Alright Knicks fans...Buy or Sell Steve Nash in a Knicks uniform?

I'm really torn on this move. Reports have us linked to him recently. Some even saying that we picked Iman Shumpert because the Suns were so enamored with him and he could be trade bait. Let me make this clear, I LIKE STEVE NASH. But at 37, he is a risk vs reward kind of player. Billups shoots just as good, but doesn't have the floor vision. And both are liabilities on the defensive end. I dont know...
