Cheatham grew up in South Phoenix and initially attended St. Mary's High School. He transferred to South Mountain High School after his freshman year, playing basketball there for two seasons before transferring to Westwind Preparatory Academy. Cheatham transferred back to South Mountain after learning the school did not meet the NCAA's academic standards and retook all of his junior courses simultaneously with his senior courseload in order to graduate on time. Ranked a consensus four star and top 100 recruit, Cheatham committed to San Diego State over offers from Arizona State, New Mexico, Georgetown, Miami and Utah.

Cheatham spent three seasons as a member of the San Diego State Aztecs, redshirting his freshman season after breaking the fifth metatarsal in his left foot. As a redshirt freshman in 2015–16, he averaged 7.9 points and 5.4 rebounds per game. In his redshirt sophomore season in 2016–17, Cheatham averaged 9.1 points and 6.3 rebounds and was named honorable mention All-Mountain West Conference.

In April 2017, Cheatham announced that he would be leaving the program.

Cheatham transferred to Arizona State University, citing a desire to play closer to home, but sat out the 2017–18 season due to NCAA transfer regulations. He joined the Sun Devils for the 2018–19 season and averaged 12.2 points and a Pac-12 Conference-leading 10.3 rebounds per game.

Cheatham participated in the NBA G League Elite Camp in May 2019. After going undrafted in the 2019 NBA draft, he was immediately offered a two-way contract by the Oklahoma City Thunder but his deliberation meant that the team instead gave it to his Sun Devils teammate Luguentz Dort. Cheatham joined the New Orleans Pelicans for the 2019 NBA Summer League and later signed a two-way contract with the Pelicans on July 24, 2019. Cheatham made his NBA debut on November 16, 2019, in a 109–94 loss to the Miami Heat, recording two points, three rebounds and one assist in 14 minutes of play.
