Johnson's collegiate career only lasted 13 games, but it was clear he had NBA-caliber talent despite the small sample size. He opened the season with a 19-point, 19-rebound outing against Coppin State, ultimately starting the first four games before a foot injury forced a brief hiatus. Three games later, Johnson was back in a limited capacity for ACC play. His highlight was a Jan. 19 contest against Pittsburgh in which the 6-9 forward produced 24 points, 16 rebounds, seven assists and four blocks. Johnson ended up logging seven games after that before ultimately electing to opt out the remainder of the pandemic-shortened season to focus on the NBA Draft.
