They were frustrated at the officiating. They were frustrated at themselves. They were just frustrated in general because of the loss.
The Clippers will have to deal with their frustrations and move on.
They can't afford to stay annoyed at all they endured in Game 5, at all the things that boiled up inside of them because of their own making and of the questionable refereeing at times.
The Clippers are one game away from being dispatched from the Western Conference playoffs, their 111-107 loss to the San Antonio Spurs on Tuesday night putting Los Angeles in a 3-2 deficit in the best-of-seven series.
So be frustrated, Clippers, because that's what you have become known for around the NBA.
But just know that Game 6 is Thursday night in San Antonio and you still have an opportunity to push the series to a Game 7 if the Clippers win the next game.
"I'll be frustrated all night," Clippers Coach Doc Rivers said. "I have no problem with guys being frustrated. They have 48 hours or whatever to get over it and we will."
Rivers admitted he was frustrated at the officials.
He wondered how they could call a technical foul on Chris Paul with 4:48 left for giving the ball to the officials after Kawhi Leonard scored.
But Rivers was also frustrated at how his younger and more athletic team allowed the older San Antonio team to "get to more loose balls" when the Clippers are the team "with the speed."
The Clippers also were frustrated with their three-point shooting.
They made just one out of 14 tries. That's not going to get it against the Spurs.
The Spurs were frustrated at times with their own play, but they kept playing through their tough times.
That's what the Clippers will have to do in Game 6.
If not, they'll have all summer to deal with their frustrations.
