I know this sound bold but I believe Spurs would have beaten them in 5. The Warriors had the same look on their faces the Spurs had in '01 when the Lakers went into their house and beat them. Warriors were scared and played scared until Kawhi got hurt. They didn't have the confidence they could win and it showed in their body language when they got dejected after the Spurs pushed the lead back to 25 after the Warriors had cut it to 10 points a few minutes earlier. Warriors would have easily folded since the mentality of their team was always that of front runners.
