One highlight of his career was in 1988 when, as a member of the Clippers, he led the league in rebounding with 13.0 per game. He was on a personal duel with Charles Oakley, who was playing with the Chicago Bulls at the time. Cage needed to register 28 rebounds in his final game to beat out Oakley for the rebounding title. He ended up grabbing 30.
During his career, Cage earned the nicknames "John Shaft" and "Windexman" (as in "cleaning the glass") for his rebounding prowess and hard work on defense.
He holds career averages of 7.3 points and 7.6 rebounds per game.
Cage and his wife Jodi have three children: Alexis, Michael, Jr. and Sydney. As a retired player, he enjoys officiating soccer games and watching his own kids play. Additionally, he enjoys playing pick-up basketball at his local Jewish Community Center in Newport Coast, California. He also has recently been inducted into the Arkansas hall of fame. His oldest daughter, Alexis, plays volleyball.
