Steph Curry had an open look from 3 so Klay Thompson did what anyone would do. He threw up his hands in celebration and started back down the court to play defense.
It turns out that he celebrated a little too early. Curry for some reason passed up the shot and threw the ball to Thompson. It has to be the only wide open shot he's passed up all season.
This play doesn't look like a play from the team with the best record in the NBA. It didn't hurt, the Warriors still won the game.
