Mark Cuban was really upset back in 2006 when the Mavericks lost to the Miami heat in the NBA finals. But nobody knew he was this upset. Many fans even to this day still feel that particular series was “suspect” to say the least in regards to the way the games were officiated. The Mavs were up 2-0 in the series before losing 4 straight and watching Dwyane Wade set a new record for free throws as well as some other sketchy calls. Cuban was so irate he actually got the FBI involved to investigate the NBA and the officiating. See what happened after the jump.
