The Bulls never have won a playoff series from the Boston Celtics, zero for four times and 3-14 in games. But they have been played some of the greatest playoff—and most famous—playoff series in NBA history.
It was in Game 2 in the 1986 first round against a Celtics team that many in Boston regard as even their best team ever that Michael Jordan scored a playoff record 63 points, essentially the career coming out party for the player many regard as the greatest ever. And doing so against the Larry Bird-Kevin McHale-Robert Parish Big Three that rolled to the title 11-1 through the East and then through the twin seven footers of Hakeem Olajuwon and Ralph Sampson.
