FOX News Radio's Nancy Singer spends a few moments with Mike "Coach K" Krzyzewski, the winningest coach in Division I college basketball. As head coach at Duke University, he led the team to four NCAA national championship titles. As coach of the U.S. men's basketball team, he brought home back-to-back gold medals in Beijing and London. But the drive and determination to overcome that has made Coach K successful on the court almost ended his career. Struggling with painful osteoarthritis in his hips, Coach K says his opponent became his pain, forcing him to make a decision he wishes he had made years earlier.
