When the U.S. men's basketball team takes the court on August 6, at the Olympic Games in Rio de Janeiro, its most powerful asset will be a five-foot 10-inch grizzled veteran with an unmatched record of wins. That would be coach Mike Krzyzewski, who led Team USA to Olympic gold in 2008 and 2012. Of the 76 games played under the watchful eye of “Coach K,” the national squad won 75. As head coach of Duke University's Blue Devils for 36 years, he has a greater number of wins—more than 1,040—than any other Division I basketball coach in the history of the National Collegiate Athletic Association. He is second all-time in national championships, with five victories.
