Since 1980, he has served as the head men's basketball coach at Duke University, where he has led the Blue Devils to five NCAA Championships, 12 Final Fours, 12 ACC regular season titles, and 15 ACC Tournament championships. Among men's college basketball coaches, only UCLA's John Wooden has won more NCAA Championships with a total of 10. Krzyzewski has also coached the United States men's national basketball team, which he has led to three gold medals at the 2008 Summer Olympics, 2012 Summer Olympics, and 2016 Summer Olympics. He served as the head coach of the American team that won gold medals at the 2010 and the 2014 FIBA World Cup. He was also an assistant coach for the 1992 "Dream Team". Krzyzewski was a point guard at Army from 1966 to 1969 under coach Bob Knight. From 1975 to 1980, he was the head basketball coach for his alma mater. He is a two-time inductee into the Naismith Memorial Basketball Hall of Fame, in 2001 for his individual coaching career and in 2010 as part of the collective induction of the "Dream Team". He was inducted into the College Basketball Hall of Fame in 2006, and the United States Olympic Hall of Fame in 2009 (with the "Dream Team"). On November 15, 2011, Krzyzewski led Duke to a 74–69 victory over Michigan State at Madison Square Garden to become the coach with the most wins in NCAA Division I men's basketball history.
