Best guess: West 3 South 2 Central 2 International 2 (Israel and Iroquois) North 7 East 8
Central only has 3 teams playing in qualifier, they should only allow 1 to advance. Dont know about Canada, they will probably have a few. It is their National Sport.
They are typically all older, so possibly not. Lots of 20 year old Canadian Freshmen in college.
