There have been players who jumped higher but MJ had it all - speed, quickness, agility, vert, wingspan and hands, and in later years, strength to post up and back down defenders, rarely got injured outside of the early foot injury and the Wizards years and was available for 82 games for most of his career and one of the highest BBIQ & legendary work ethic and competitiveness to maximize his god given abilities. Was really a cheat code.
