“It’s just basketball.” It’s something that Gregg Popovich will often say. Whether you win or lose, you move on. Keep doing what you do and try to do it the best you can.
However, this kind of attitude doesn’t exclude competitiveness. In fact, Spurs don’t like to lose. Really. They react to losses very strongly, coming into next game with extra amount of effort and focus.
First of all, only twice this season have the Spurs lost two games in a row (Clippers/Rockets, and Pelicans/Mavericks). This could be a positive sign heading to the playoffs, keeping composure after losses and responding quickly and strong.
