The Suns aren't the same team anymore- they've stopped running. In truth the Suns might be better off with Andre Miller running the team, as he is a better scorer than Nash.
There is no way the Sixers give them more than Miller for Nash anyway. Steve is old and as much of a defensive liability as Miller. Steve is a much better passer and would be a better fit in Phila. but I wouldn't make that trade as the Sixers should be able to find a suitable point guard for less.
Very few teams are going to be willing to chase after Nash with what Phoenix is paying him.
