The point guard came off the bench to score 21 points during the 108-98 victory.
His opponent told reporters: "He threw up some crazy shots. That's when you know a guy is having a good night.
"They would put one up at the end of so many good defensive possessions, and it's going in. That let you know what kind of night it was."
