Richardson sounded off on both Garnett and Pierce after the game.
"I was trying to get over there to take the ball out of bounds and [Garnett] started to talk to me, so I talked back. I don't have any business talking to him, he was on the ground crying. I don't know what was going on, two actresses over there, that's what they are.
"I just get surprised by people's actions when I know them better than that. They're not those characters they portray. They're not who they say they are, Garnett and Pierce, they're good basketball players and that's about it.
"I said to Jermaine, he's OK because I knew nobody touched him," explained Richardson. "Is he taking another break like he does so many times? Sometimes he falls like he's about to be out for the season and then he gets right up, that's all I said.
"I don't like them, and they know it."
