I don't think Cuban owned him at all. I think Cuban made some good points, but he also got hit with the biggest haymaker from Smith on the Odom point. Cuban is right that there is a lacking of facts to back things up (you can clearly tell which people do their homework), but a lot of time they show you the stats then talk about the softer science of sports.
Cuban trying to give all credit to his team is obviously a pride thing - they deserve a lot of credit, but he makes it seem like there is no such thing a choking. There clearly is.
