Schea Cotton, whom Kevin Garnett once referred to as “LeBron before LeBron,” was scheduled to debut a screening of his documentary “Manchild” on Saturday in Los Angeles.

Cotton was considered the best prep player in the nation in the early 1990s, even dominating Garnett in an AAU game despite being just 6 feet 4 inches.

Cotton eventually played at Alabama and then overseas with his only NBA exposure was playing for the Magic’s summer league team in 2001 and the Clippers’ summer squad in 2003.

“Manchild” focuses on Cotton’s journey as a prep phenom and the disappointment of falling short of reaching the NBA.
