Bill Sharman, American basketball player and coach (b. 1926)
William Walton Sharman (May 25, 1926 – October 25, 2013) was an American professional basketball player and coach. He is mostly known for his time with the Boston Celtics in the 1950s, partnering with Bob Cousy in what was then considered the greatest backcourt duo of all time. As a coach, Sharman won titles in the ABL, ABA, and NBA, and is credited with introducing the now ubiquitous morning shootaround.

He was the first North American sports figure to win a championship as a player, coach, and executive. He was a 10-time NBA champion (having won four titles as a player with the Celtics, one as head coach of the Los Angeles Lakers, and five as a Lakers executive), and a 12-time World Champion in basketball overall counting his ABL and ABA titles. Sharman is also a two-time Naismith Memorial Basketball Hall of Fame inductee, having been inducted in 1976 as a player, and in 2004 as a coach. Only John Wooden, Lenny Wilkens, Tommy Heinsohn and Bill Russell share this double honor.
