Only football-related ones I have are Backbreaker and Kick Off. Neither one of them are really full football games, though. Kick Off is basically just flicking the screen to kick fieldgoals, and Backbreaker is fun, but you really only run the ball. The point of it is to score as many points each time you run, and you get points for avoiding tacklers (spin moves, jukes, or just dodging them), and there are bonus zones you run through for more points. So not a full football game either, just running and avoiding defenders over and over.
