I don’t understand how this is fair, due to one group having six and the other 5 teams. Surely the group with five have an advantage, due to them playing more games - more likely to win at least two.
While this is fair, would you really want a team that goes 1-4 (20% WR) to make playoffs? Doesn't seem fair for a team on the otherside who likely goes 3-3 (50% WR) in this case to miss playoffs.
