34. John McEnroe
Who And Why: Tennis bad boy, rebel
Years Of Influence: 1977-1992
John embodied the bad-boy mentality. And tennis has a lot of great, great players today, but I don’t see them bleeding competitiveness the same way John did. They’re almost robot-like nowadays. And the thing about John, he was the top player during his time and he wasn’t even playing in tennis shoes! He wore cross-trainers. As a sneakerhead, it made me believe in that movement. It was a genius move.
