Steve Nash on the trading block?

Is Nash really on the block, or is that just heresay? From my calls around the league, I think it's more conjecture at this point. The Suns don't look like a playoff contender in the early going and Nash is the one asset they have that could get them something important in return. But I've yet to talk to a league source inside or outside the Suns who has told me they know Nash is available. But I understand the thinking and wouldn't be shocked if he was wearing a different uniform in February. ESPN.com
