Nice post.
Coming into the NFL draft after his junior season, Achane has averaged about 15.5 touches per game over his college career. For comparison, Alvin Kamara came out after his sophomore year and averaged just under 12 touches per game.
For another comparison, Leonard Fournette racked up 300 rushing attempts in 12 games as a sophomore (25/game). Then as a junior he was in and out of the Tigers' lineup, eventually only being available for 7 games that season.
