Maybe you just don't understand the nature of rankings... they aren't guarantees of outcomes... rather they are meant to identify the probabilities of outcomes. With Wave 1 having a record of 23-0-1, and winning their regional Silver Stick tournament, I think it is fair to say they deserve to lead in the SCAHA PW A rankings. It certainly doesn't guarantee they will win any game they play (and there will always be upsets-- that is why the game is played in the first place), but if their ranking is higher than their opponent, then they are more likely to win.
