But quite possibly the best reaction came from his sister Sydel Curry-Lee, who was watching on TV with her husband and Warriors guard Damion Lee.
Based on Sydel's Instagram Story, she was on the edge of her seat the whole time Curry was shooting.
Curry needed a late push to top Utah Jazz guard Mike Conley in the final round. He got to the final rack of balls with 23 points, needing five points to beat Conley.
When Curry got to the final ball, a money ball, he trailed Conley 27-26. The Warriors' star nailed the winning shot and Sydel couldn't contain her excitement. Lee was a little more subdued, but still excited for his brother-in-law and teammate.

In a funny twist, Sydel was embarrassed by her reaction to Steph winning the contest.
If it makes Sydel feel any better, just about everyone in Dub Nation had the same reaction as her.
