the 01-02 lakers have now also done this by beating the twolves (50), kings (55), spurs (58), and sixers (56). however, all four of our opponents had at least 57 wins and 2 had 60, which the lakers' opponents did not (and the state of the east at the time makes it even less impressive). of course the lakers went freakin' 15-1 in the playoffs.
