While a lot of that is true, it was just one game and in most cases, one game's result rarely transfers over to the next game when two teams are pretty evenly matched.
Spurs beat the Clippers 100-73 in game three, 2015 and lost the series in seven.
Spurs beat the Thunder 124-92 in game one, 2016 and lost the series in six.
The Rockets shot from three point range vs a pretty mediocre Thunder defense...
Game 1 - 10-33
GAME 2 - 11-29
Game 3 - 10-35
Game 4 - 11-35
Game 5 - 6-37
Game 1 vs Spurs 22-50 (44%)
The series is far from over and I don't expect the Rockets to shoot nearly 45% from three on 50 attempts per game. The Rockets played a near flawless game while the Spurs played one of their worst postseason games ever.
