Not to be overly pessimistic but....
Those national rankings are only for schools playing in the spring AND only for teams whose coaches are members of the NCSAA AND from what I understand, the coach has to recommend (for lack of better word) their team for ranking.

I agree G'vegas and NW are good teams, but it is rather humorous to read in the HS section that a SC is #1 in the nation but read in the other sections how SC may not be up to par with the rest of the country.
