John Havlicek--beating people mentally, not physically

John Havlicek of the Boston Celtics, was a true genius when it came to using conditioning as a weapon. His goal was to get his opponent to give up, to stop overcoming fatigue, to stop pushing himself. Havlicek saw it as a matter of who gives up first. "You'll pass out before you're overworked, but most people don't know that," he once told Orlando Magic senior executive vice president Pat Williams. "They think they're overworked, so they stop. They could have kept going, but they didn't. They weren't beat physically; they were beat mentally."
