1. Mark Cuban, Dallas Mavericks
Since Cuban took over, the Mavericks have enjoyed unquestioned success. We have to credit Cuban for that. The problem is that Cuban is also a shameless self promoter. If this was a matter of promoting his team, we’d be okay with it. But consistently promoting yourself for the better part of two decades? We have to call you out on that.
Cuban’s most common frustration has been geared towards the NBA’s officials. For the record, Dallas has lost games and even playoff series that had nothing to do with poor officiating. A few Mavericks wins have also been aided by poor officiating. You just wouldn’t know any of that by listening to Cuban, who seems to believe that the referees are in place just to hurt him and his teams.
But even without complaining about officiating, Cuban has compiled quite the blowhard resume for himself. He clearly does not think that Russell Westbrook is a superstar. But how would Cuban react if someone made even a joke at Dirk Nowitzki’s expense? Not well, and we know this for a fact. Cuban no only threw a tantrum regarding a fairly innocent Nowitzki joke, but essentially bragged about it.
Following one playoff game against the Denver Nuggets, Cuban yelled at Kenyon Martin’s mother, calling her son a “thug.” That kind of behavior is unacceptable for anyone at a sporting event. For an owner in his 50’s? It’s beyond unacceptable.
Cuban is not only one of the NBA’s most annoying personalities, but he’s arguably the biggest blowhard owner in any sport. He’s worked hard to earn the title.
