My original question has to do with conditioning requirements. In US football, most of those guys llok for strength with zero endurance. In rugby, it appears that the players have to be in better shape, since the game doesn't stop for timeouts and cahnges in the entire lineups.
      As a high school and college wrestler, who also played football, my experience is that football players don't have any idea about conditioning.
      My prefernce is to watch ANY soccer game, including pre-schoolers, over any football, baseball, or basketball games.
