Cuban is an amazing owner and some people give him a bad rap because he speaks out and is a huge non-conformist. He speaks his mind and isn't afraid to say what he wants, stand up for what he believes, or call people out when they need it. He spends money to see his team try to compete and trying to make his fans happy.
Most of all, his IQ on the sport of basketball is ridiculously high. I love the clip of him on whatever panel it was (first take maybe) where Skip Bayless tries to call his team out by saying LeBron had a bad series or something. Cuban just laid into him and broke down the entire Mavericks gameplan, why and how they did everything it did, and the effects and positive causes of every move they made. It was really quite genius.
I hope he does draft Griner. Great PR, great political move, smart basketball move? Probably not but hey, stranger things have happened.
