If you mess with these Bulls on the court, you might get the horns. Chicago Professional Sports owns and operates the Chicago Bulls professional basketball team, which boasts six NBA championships thanks to five-time MVP Michael Jordan. His charismatic presence not only set a high-water mark for Chicago between 1991 and 1998 but also helped increase the popularity of the league. The team was started by Dick Klein and joined the National Basketball Association in 1966. Real estate developer Jerry Reinsdorf has owned the Bulls since 1985. He also owns Chicago's United Center (along with Chicago Blackhawks owner the Wirtz Corporation) and the Chicago White Sox baseball team.
While the Bulls maintain a loyal following in the Windy City, Reinsdorf has shouldered much of the blame for the lack of championship performances since His Airness left the team in 1998. (Some still blame the owner and then general manager Jerry Krause for driving away Jordan and head coach Phil Jackson.)
The franchise hired Tom Thibodeau as head coach in 2010, replacing Vinny Del Negro after two seasons. A veteran assistant coach with the Boston Celtics, Houston Rockets, and New York Knicks, it was Thibodeau's first appointment as a head coach. Del Negro, also a first-time head coach, had replaced Scott Skiles and led the Bulls to two consecutive playoff appearances.
