Michael Jordan’s playoff on/off data has now been tracked in full on Basketball History Database. For his postseason career, the Bulls had a +7.7 net rating with him on the court and a -10.4 net rating with him off the court, giving him an on/off of +18.1.
Because I’m sure someone is going to bring this up LeBron’s career playoff on-off is +9.5 and through age 35 which is the age when MJ played his last playoff game it was +10.5
Jordan seems to clear everyone who came since him by a solid margin the other 21st century guys to always check for on/off stuff are Garnett and Curry who are at +14.5 and +12.0 respectively
