how long do you have to be in college before the nfl
National Football League Draft 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.
High school football The regular season typically consists of ten games in most states; Kansas is one of the few states which limits teams to nine. Teams in Minnesota usually play eight,[5] while teams in New York typically schedule only seven. The first game of the season is usually in early September, or late August, and the final regular season game is usually in mid to late October, with the end of the season varying by state and climate. Teams may have one or more bye weeks during the regular season. Larger schools (especially those with successful programs) can often draw attendances in the thousands, even for regular season games, and in some cases may play the game at a college or professional stadium to accommodate the expected large crowds.
