Using the KHSAA comparison...
Trinity is usually the cream of the crop in 6A and statewide. If we applied the same logic to high school that we do for college, that would mean we always think 6A is the best class because Trinity and Male dominate.
How many years do we really think that after Trinity and Male, the next several "best" teams are all in 6A? Not often.
Having the best team, or even the best two teams doesn't make a league the best.
