Tim Duncan spent his entire 19-year career with the San Antonio Spurs — and this week, he came out of retirement to join the team’s coaching staff as an assistant coach.

“It is only fitting, that after I served loyally for 19 years as Tim Duncan’s assistant, that he returns the favor,” said Spurs head coach Gregg Popovich.

Popovich joined the Spurs organization in 1996, then Duncan was drafted by San Antonio as the first overall pick of the 1997 NBA draft.

The player-coach duo went on to win five NBA championships together, in 1999, 2003, 2005, 2007 and 2014. Duncan, now 43, retired after the conclusion of the 2015-16 season. Popovich is 70 years old and still going strong.

So that got us thinking: What other duos have dominated sports? And it got us thinking even further: With Popovich and Duncan on an already stacked coaching staff that includes Becky Hammon, is this officially the start of a new dominating era for Spurs basketball?

Long-term winningest player and coach duos (10-plus seasons)

Short-term winningest player and coach duos (Five or fewer seasons)

Duos too good to leave out but didn’t fit in either category
