Though he looks miserable here, Celtics coach Glenn "Doc" Rivers
no doubt enjoyed guiding his team to the best record in the NBA this season.
Rivers was a longtime NBA point guard -- best remembered for playing alongside Dominique Wilkins with the Atlanta Hawks -- but for all his success, he never won a title. If he's to win one as a coach, he'll need to match wits with the Lakers' Phil Jackson, arguably the most successful coach in league history. (Elsa/Getty Images)
