There's a surprisingly big cultural chasm here. Acrington Stanley are a football club, that's not so weird - the US has plenty of professional sports teams and distinguishes "major" leagues, but AIUI the US doesn't have anything like the "Football Pyramid": https://en.wikipedia.org/wiki/English_football_league_system

If the Green Bay Packers lose every game, I think they're just back next year anyway like nothing happened? If Manchester United lost every game they're relegated and cease to be in the Premier League, some team you've never heard of which won the EFL Championship become a Premier League team next season [subject to various extra rules they can probably meet] and Man U take their place in the EFL Championship.
