I was listening to the Sid and Tim Uncut podcast (which I suggest any sports fan to listen to, it's free on iTunes) and they said something interesting about Phoenix. If Amare leaves, Nash is pretty much by himself, you think he can make a call to a certain German center? They ran shit in Dallas.
I'll have to check out that podcast. Plus it's free so can't go wrong with that. But as far as Dirk goes, I don't see him leaving Dallas. At least not now anyway.
