"Sometimes we forget how much we love the game, and when you don't play, you appreciate the game better," said Casspi, who had four rebounds and two points in 12 minutes off the bench against Denver. "I'm just happy to go out there and have fun."
Casspi was a spark in Tuesday's win over Phoenix, and Westphal praised the second-year forward for handling the situation professionally.
Sitting wasn't easy for Casspi, who has started 27 times this season, but he maintained the same approach.
"Be the professional you need to be and be ready when it's time to go out and play," Casspi said. "It's hard to be the three on this team because we don't run a lot of plays for us. Just be ready."
