He took a pay cut after his 2nd retirement, not his first.
Not that Jordan didn't deserve it, but that salary is crazy. He made $30m in '97, and $33m in '98. It took until 2013 for another player, Kobe Bryant, to finally break the $30m mark again.
Look at everybody else in '98. Shaq made $13m, Mourning made $11m, Hakeem made $11m, Karl Malone made $5m, Barkley made $2m, Gary Payton made $11m, Penny Hardaway made $8m, Patrick Ewing made $20m, Juwan Howard made $11m, etc. Kevin Garnett signed a contract during the '98 season that would pay him $14m in '99.
The average salary then was $2.37m, the average salary now is $5.15m.
I think the NBA's revenue has basically doubled in that time frame. From about $2.5B to like $5B. That would be like the equivalent of Kobe or LeBron making $66m last year.
Crazy, but he was worth every penny, if not more.
