What is the coaching philosophy of NBA Spurs coach Popovich?

Popovich's teaching philosophy is "details determine success or failure". He believes that starting from small things, the Spurs attach great importance to the detailed training of players. He once bluntly said: "A person can't be both a good coach and a good temper. Coming out of the army, I know how to improve the tactical execution ability of the team. You must constantly urge and even anger the players. "
