First of all, I would like to thank the legendary coach of the Spurs, Popovich. Born in the US Air Force, Popovich 1997 began to coach the Spurs and led them to lift the O 'Brien Cup four times. Popovich has a tough style and strict coaching. He brought a rigorous style to the Spurs, requiring players to strictly implement tactical arrangements, build a solid defense, and not allow random and unnecessary mistakes. During the 15 season when he coached the Spurs, the Spurs made the playoffs every year, and he was undoubtedly a successful helmsman.
