In Michael Jordans 37 playoff series, he faced 269 different players. He outscored 268 of them. The only player to ever outscore MJ in a series was Terry Cummings, who did it by a single point in MJ's rookie year by avging 29.5ppg

After reading the Hakeem post I took a cursory glance at MJ opponents and found that in all but 1 case, he's outscored every single player he's ever faced in a playoff series.

Terry scored 118 points to MJs 117 for the Bucks in the 4 game EC round 1 in 1985. It was MJ's first ever playoff series in his rookie year and he was guarded by 2x DPOY Sydney Moncreif, holding him to 29.3 a game. In his next playoff series he would average 44ppg, outscoring Larry Bird (who still put up a fantastic 28ppg) by 16ppg and would outscore his opponents in the following 36 playoff series.
