When the 1972 Los Angeles Lakers went 69-13 (a .841 winning percentage), it appeared to be one of the several NBA records that might be insurmountable, and for a while it was.
But 24 years later, on April 21, 1996, Michael Jordan and the Chicago Bulls surpassed it, beating the Washington Bullets to claim their 72nd victory of the season to finish 72-10 (a .878 winning percentage).
Jordan was stellar in the victory, as one would expect from not only arguably the greatest player of all time, but also one of the most competitive. Jordan dropped 26 points on the Bullets, going 11-22 from the field in the win.
