Phil Jackson Retires
May 8: The “Zen Master” said early in 2011, “This year, there’s no maybe,” referring to his decision to retire after the season. Following the Mavericks’ sweep of Los Angeles, Jackson stuck to his word and stepped out. He’s the only coach in the country’s major professional sports to have won at least 10 championships and has the highest winning percentage of any coach in the NBA Hall of Fame.
