The league's sixth-most winningest coach actually began his NBA career as a point guard for the San Antonio Spurs, originally of the ABA, and then remained with the team after the merger until 1978. George Karl spent parts of five seasons with the Spurs, averaging 6.5 points and three assists over 17 minutes for his career.
Once his playing days were over, he took an assistant coaching job with San Antonio, which was only the beginning of Karl's famed coaching career. With five teams over 25 seasons as head coach, Karl's teams missed out on the playoffs just three times. His offenses were often free-flowing, fun to watch, and effective. He won 50 games in 12 of his 25 campaigns. His best unit was likely the 1996 Sonics team that he led to 64 wins and a Western Conference title. Shawn Kemp and Gary Payton both averaged 19 points for Seattle that year.
Karl was curiously canned by the Nuggets after winning the Coach of the Year award in 2013, and at 63, may look to re-enter the coaching scene in the near future.
