You wouldn't be saying that about Dirk if he didn't play for the Mavs.
Nash is completely more valuable. Look at who he made better on that team. I mean, have you actually watched him play? He can get the ball to a better shot, rather then just taking it himself. And, if nothing else is open, he will shoot, and he is pretty good at that.
Easy, if the Mavs didn't have the best record and/or Nash didn't win it 2 years straight, he easily deserves it.
Dirk choked, and Nash isn't. Also, you absolutely have to admit that Dirk choked. It isn't just that they got outcoached, he just didn't score. He shot, didn't make it. He wouldn't go to the rim.
Nash deserved it, end of story.
