The Spurs could turn to former players
When looking at the best options for the Spurs to consider, it seems very obvious they could easily bring back a beloved former player. Many players, like Monty Williams, Alvin Gentry, and Doc Rivers, are already head coaches and seem comfortable in their roles. It’s entirely possible that the San Antonio Spurs bring back a former player with very little coaching experience.
Manu Ginobili - Manu Ginobili was a two-time All-Star, a four-time champion, and an elite on-court presence for the San Antonio Spurs. He has since retired and come aboard as a Special Advisor to Basketball Operations and has taken on a significant role in player development for the rebuilding Spurs. By all accounts, he has a hugely positive presence at practices and is very valuable to the development of the current Spurs.
Manu has very little coaching experience but with the right co-cast of assistants on the bench, it would not be far-fetched to say Manu could see success.
Tony Parker - Tony Parker has always made it clear he wanted some sort of front-office role after he retired from playing, and he has already found that as the owner and president of ASVEL Basket in France. He also has very little coaching experience but hired his younger brother, TJ, to coach ASVEL.
While he has very little coaching experience, Popovich himself was President of Basketball Operations before stepping up and becoming the greatest coach ever, so clearly it can be done.
David Robinson - David Robinson has remained very active in the community since retiring and has made a massive fortune as a savvy investor. A military man, Robinson certainly has the discipline and respect to lead a team, but he does lack the experience. His charity and other ventures probably come first, so the Spurs announcing him as head coach would be a massive surprise.
Tim Duncan - Tim Duncan is the greatest Spur ever, a top-five NBA player ever, and the greatest power forward to ever play the game. He is also undefeated as a head coach. In March of 2020, Popovich missed a game for personal reasons and Duncan took over. The Spurs won.
He has since stepped down from his assistant coaching duties but still holds an advisory role. This move would appease fans more than any other, and there’s reason to think he would find success. Like many other former players, he is still very active in the San Antonio community, so he’s just a phone call away.
