Watch: Klay Thompson misses a buzzer-beater in Dallas

It was a difficult night overall for Thompson, who scored just five points in a game where the Warriors overcame a 17-point first quarter deficit. Not only Golden State lose, but Thompson had to send the game to overtime on TNT, where Charles Barkley would have to talk about his heroics.

A month ago, Barkley said Thompson was "not the same guy" as he was before the injuries that cost him two-and-a-half seasons. Thompson said Barkley's criticism stung him. "It just hurt my heart hearing that. But you know what? I’m gonna internalize it and it’s gonna be fuel for me to be even better."

Thompson proceeded to up his scoring to 19.3 points per game in November, and shoot 43.4 percent from three-point range. Perhaps he was pressing too much due to Barkley's "fuel."

For his part, Barkley told Taylor Rooks that Thompson "100% overreacted" to his comments, and said he was "still a heck of a player."

Thompson has shown flashes of the old Klay recently, making 10 of 13 threes against the Rockets ten days ago. Unfortunately for the Warriors, he wasn't the same guy last night.
