Klay Thompson was benched with the Warriors behind by ten points in the fourth quarter on Saturday night. This is not rare. With 8:28 left, he’d almost certainly return for the final minutes, especially if the Warriors made a late run.

They did it. With 2:47 remaining, Chris Paul’s steal and 3-pointer pulled them within five points of the Dallas Mavericks.

What’s unique is that Thompson never returned. From the bench, he saw the final eight minutes of a 132-122 loss. Even as Golden State sliced the deficit in half, his displeasure was palpable.

Thompson played 26 minutes and scored three points, his season-low. He shot 1-of-11 from the field, including 1-of-6 from long range, and added two rebounds and one assist. He just had one turnover, but it set off a 13-0 Dallas run that increased its advantage from three to sixteen points in less than three minutes during the second quarter.

The Warriors never got closer than three points again.

Klay sat on the bench, clearly dissatisfied with a performance that rates among the worst of his career. His displeasure was visible on his face and in his body language. He appeared distressed and lost in contemplation. The moment was difficult to see, given that he has been a rock for the most of his career, which began in 2011.

Such attitudes are unfortunate, especially coming from one of the team’s seasoned leaders. It was a horrible look in what was another low point, possibly the lowest one, in a season with far too many lows and far too few highs for someone with Hall of Fame credentials.
