2012 Charlotte Bobcats
The great Michael Jordan headed a consortium in 2010 that bought the Charlotte Bobcats. In their first season after the change of management, they had more wins than losses. But that was it. Things went south after that. The team played 66 regular season games in 2012 and only won 7. What made things worse is that the team lost its last 23 games. They ended the regular season with a measly 0.106 percentage.
