Complex Says: Bulls versus Pistons was more than a rivalry. It was like Hatfields versus McCoys or Bushes versus Clintons. Pure hatred right there. After getting bruised up by the Pistons in the '89 and '90 playoffs by utilizing the infamous "Jordan Rules" defense, his Airness and friends finally climbed the mountain that was the Pistons by sweeping the Bad Boys in four games in the 1991 Eastern Conference Finals. The Bad Boys were so pissed they walked off the court with :04 remaining on the clock, refusing to shake hands with Jordan and the Jordanettes. Bad boys, bad boys, what 'cha gonna do?
