From TBJ:
"On the biggest possession of the game, Mugsy had the ball with the Hornets down 1. Jordan backed off of him and told him: “shoot it you f—ing midget.” Mugsy shot it, didn’t come close. A year later Mugsy actually told Johnny Bach that he believes that single play ruined his career. His shot never recovered."
