11. Mikhail Prokhorov – Brooklyn Nets
Apart from their move to the Barclay Center, the Brooklyn Nets didn’t have a good time under Prokhorov. As the first non-American franchise owner in NBA history, he came into the league with a level of mystique around him. That turned to disbelief when it became clear that he was totally hapless.
He tried to run against Vladimir Putin for the Russian presidency. In sum, that should tell you all you need to know about his decision making. He traded the likes of Gerald Wallace and Kris Humphries for over-the-hill stars like Kevin Garnett and Paul Pierce. They won one playoff series during his decade in charge – definitely not successful.
