The team is third-to-last in the league in rebounding, averaging only 40.9 a game.
"I thought we had very little impact on the ball all night," Rivers said. "And their guards got to the paint, our bigs had to help, and usually when that happens you give up offensive rebounds."
The Heat had 15 offensive rebounds. The Clippers had six.
Rivers was quick to say that Jordan should not receive the brunt of the blame for the Clippers' off night.
