He is only a sophomore. Not exactly sure if he meets the eligibility rules.
Players that have been out of high school for at least three years are eligible for the NFL draft. The rules do not state that a player must attend college, but virtually all of the players selected in the NFL draft have played college football. A year as a redshirt player in college counts toward eligibility even though the player was not allowed to participate in games during that year, therefore players who have completed their redshirt sophomore year can enter the NFL draft.
