With his team eight games under .500 for the first time since his first few months as the Dallas Mavericks’ owner, Mark Cuban is firing away at one of his favorite targets: NBA officials.

“Im sorry NBA fans. Ive tried for 13 yrs to fix the officiating in this league and I have failed miserably. Any Suggestions ? I need help,” Cuban tweeted after the Mavs’ 99-96 overtime loss Saturday night to the New Orleans Hornets, the team with the worst record in the Western Conference.

After Vince Carter’s 3-point attempt at the buzzer bounced off the rim and to the hardwood, Cuban marched to midcourt and engaged in an animated discussion with referee Bill Kennedy.

Via email, Cuban declined to specify why he was upset with the officiating after the Mavs’ eighth loss in nine games or otherwise elaborate on the incident.

However, prior to the game, Cuban complained about the officiating late in regulation of the Mavs’ overtime loss to the Miami Heat on Wednesday, a game he watched from his vacation home in the Cayman Islands.
