Until those private schools start accepting Special Needs kids and problem students that do not play sports at the same rate as they do the rest of their population, there is no way they are on a level playing field, even if they dont "cheat" and recruit athletes. Having their own division is the most logical move.. But if that isnt going to happen. Leave in the success factor but also make them play up one class regardless of success to make up a little of the unfair advantage they have built in.
