With the series tied 2-2 and the heavily favored Clippers in a dogfight with the Mavericks, Rivers said that he saw the Clippers “cave in” when Dallas made a huge run and that he has to do a better job of getting the second-seeded team in the West right for a crucial Game 5. “Honestly, I thought we were very emotionally weak tonight,” Rivers said. “… If I knew [why], I would be Sigmund Freud. But at the end of the day, we’re up 20, and we’re getting technical fouls. Things like that give the team juice. Throughout — and I’ve been saying this for three games now — we’re so much better than what we’re playing. But honestly, give Dallas credit. … They’re minus [Kristaps] Porzingis. But they just kept playing. They played together. They moved the ball.
