I think you are putting too much emphasis on the goal differential, don't get me wrong, those are some strong numbers. The current SOS is not working in your favor, upcoming matches will help this number. Another thing to look at are games you "should" win. In terms of the Maher Rankings, if you were only favored to beat Mason Co. by a couple of goals, the result the other day will help you in their rankings.
Beat a few teams that are ranked higher than you and I think you will start seeing the rankings closer to what your expectations are.
