What's funny is Ballmer is still only the 2nd worst owner in Clippers history.
I would like to mention Irv Levin, who in my opinion, did one of the worst trades in NBA history.
In 1978, Boston Braves owners John Brown and Harry Mangurian traded their franchise (the future LA Clippers!) for Irv Levin's franchise, the Boston Celtics. Mangurian bought out Brown, and they landed McHale, Parrish, and some guy out of Indiana State, won an NBA title, and then he sold the team in 1983 for $17 million (not sure on exact number).
So Irv Levin traded the Celtics to become the owner of the Boston Braves/San Diego Clippers. 3 or so years later, he sold the Clippers to Donald Sterling for $12.5 million.
