Boone was rated as a wide receiver by high school recruiting services, as he caught 57 passes for 1,068 yards and 18 touchdowns for Baker County High in Florida. It's easy to see why he chose to be a tailback for the Bearcats, however, with his compact build and bullish running style. Coaches thought he would redshirt to learn a new position, but they were forced to play him due to injuries; Boone ended up leading the team with 650 rushing yards (just 101 carries) and scored nine times in nine games. He played in 11 games (one start) the following year, covering 749 yards and nine scores on 104 totes while splitting time with Hosey Williams. Boone's junior year was somewhat disappointing (105 carries, 388 yards, two touchdowns, 20 catches, 249 receiving yards, 21 kick returns for 506 yards in nine games) because of lingering injuries, including a foot malady that ultimately cost him the end of the season. He still played in 10 games, starting nine, as a senior in 2017 (110 carries, 484 yards, four touchdowns; 24 catches, 177 yards, one touchdown reception).
