It is hard for me to accept the premise that a team that makes the playoffs and wins games in the playoffs didn't deserve to be there. Montana and Davis were ranked teams, of course they should be there. Are you saying the playoffs should only have been a 4 team playoff if you are going to exclude Montana and Davis?
As to your last point, that math just isn't real. No offense, but it is not. When was the last year there were only two teams with above a .500 overall record in the Big Sky? I cannot remember one.
