Gregg Popovich and Tim Duncan among winningest coach-athlete duos in sports history

Gregg Popovich is the NBA's all-time winningest coach.

Popovich passed Don Nelson's NBA record with his 1,336th career coaching victory in the San Antonio Spurs' 104-102 win over the Utah Jazz on Friday night.

Popovich is currently in his 26th season with the league. After joining the Spurs as an assistant coach in 1988, he spent two seasons on Nelson's Golden State Warriors' staff before returning to San Antonio in 1994 as general manager and vice president of basketball operations. Midway through the 1996-97 season he took over as head coach of the Spurs.

A large part of Popovich's success was achieved alongside eventual Hall of Famer Tim Duncan, who was selected by San Antonio as the first overall pick of the 1997 NBA draft. With Popovich at the helm and Duncan on the court, the Spurs won the NBA title in 1999, 2003, 2005, 2007 and 2014. Duncan retired from the NBA in 2016 after 19 years with the franchise.

As so much of Coach Pop's success in San Antonio was tied to his partnership with Duncan, his latest feat got us thinking, what are some other wildly successful player-coach duos across sports?

Ryan Giggs and Alex Ferguson (21 seasons and 13 Premier League titles): If you've been knighted by the Queen of England, you're clearly a sports legend. Sir Alex Ferguson racked up one heck of a résumé throughout his 26-year tenure with Manchester United, winning a total of 38 trophies — including 13 Premier League titles, five FA Cups and two Champions League titles. During those 26 years, Ferguson had star midfielder Giggs on his squad, who spent his entire professional career in sheer dominance with the Red Devils (1990-2014).

Tom Brady and Bill Belichick (20 seasons and six Super Bowls): Do we even need to remind you of
