I've said a lot of bad things about Dirk, but that guy brings it. I think that Cuban and Nelson are an absolute horrible combination. They need to trade for a big man no matter what.
But I do think that Dirk is clutch, and I do think he has championship qualities, as does Romo.
I think Romo has mad skills. But I think Romo wants to be super man, and Garrett wants him to be as well. In stead of Garrett grabbing a hold of Romo and telling him to stop flinging the ball all over the place, he lets him go.
All in all, I think you have to build a team around both these guys, I think the Cowboys are closer to that than Dirk is, and once you have that team around you, you have to have clutch performers, not just the Super Stars.
