Yeah, I'd agree on Arenas. But when he's on he's devastating. I think he's 10-10 on 30+ foot shots this year. Doesn't really add to anything, just a neat stat if it's true.
What gets me about Nash, and has for the past two years, is the fact that he has Amare Stoudemire and Shawn Marion. Those are two top tier NBA players on your team. And personally, I think Marion is more valuable to the Suns than Nash.
