You forgot West Carleton at #16 in triple A ofsaa.
I think that the St. Pats and Ashbury seeds are fair, but I thought Immaculata would be a litter better (5 or 6?). Unless I am missing something, they have only lost to two teams all season (Jean Mance from MTL and Ottawa's St. Pats) and one of the teams is ranked third at AAA. The only reason I can think of for this is that I don't think that they played anyone from southern Ontario.
West Carleton has to be one of the better 16 seeds at an ofsaa tournament. They have a nice matchup against the 6th seed (St. Theresa) in the first round and if they can win it, they will take the 6th seeds path. It won't be an easy game, but I think it is one that they will compete in. This could mean a quarter final show down with St. Pats.
