How many championships have the bulls won?

Six!! All with Michael Jordan and Scottie Pippen. 1990-91, 1991-92, 1992-93, 1995-96, 1996-97 and 1997-98. Greatest team of all time, because Jordan is best player of all time. Would have won at least eight consecutive championships if Jordan hadn't "retired" to play Baseball in 1993-94 and 1994-95. Probably could have won two more championships after last one if coach Phil Jackson had not left, resulting in Jordan and Pippen also leaving the Bulls.
