how many years of college football do you have to play to go pro
Players who 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, usually in the United States but occasionally from Canadian universities as well. A few players are occasionally selected from other football leagues like the Arena Football League (AFL), the Canadian Football League (CFL), and the German Football League (GFL). A small handful of players have also been drafted from colleges who played other sports than football.
