So the 12-0 team played 12 0-12 teams? And the same season there existed a 0-12
team that lost every game by 1 to 12 12-0 teams. Odds are that one of the 0-12 teams that the 12-0 team beat is the 0-12 team that lost every game by 1 to 12 12-0 teams. So the 12-0 team is better since it beat the 0-12 team.
