Yes, you are making my point. In football they have divisions based on enrollment I think 6A 5A etc.
Its not a 100% always based on the enrollment, it just helps, if a school has 1000 and another one has 1001, the bigger one won't always win, but the bigger the difference the more likely it will factor.
ANSWER THIS: If you combined Naperville North with Waub. and the other school, with the extra people to choose from do you think you would be better or worse. Do you think if New Trier Highschool split to New Trier East and West would each team be better or worse than New Trier combined. If Glenbrook North and South combined and picked the best players to play Varsity would they be better then each of the individual teams or worse?
