Mark Cuban
Cuban is one of the most visible owners in the NBA today but he polarizes fans. That’s because he made mistakes that people can’t understand. One of these saw him shake hands with DeAndre Jordan after apparently signing him for the franchise. But Jordan didn’t sign anything and rejoined the Clippers (via The Sports Rush).

Meanwhile, Cuban refused to pay Steve Nash and lost the star point guard to the Phoenix Suns. It was a terrible decision but Cuban didn’t want to break the bank. Furthermore, Cuban’s personality grates many basketball lovers because he wants everybody to like him. Inevitably this means that many of them don’t want to hear about him.
