What about the private schools that are small in a large population area? how do you fix that issue. St Alberts in CB, they are A in football and have a HUGE area to cast a net too. and play against population basis that are far smaller than theirs. So say they lose a kid, well there are plenty more for them to choose from. Take for instance their basketball squad. have 15 suited up with only 2 sophmores on the roster. When they lose a solid senior class, like this years actually, they continue to be competitive to the point of pushing a state tournament appearance every year. teams they have to compete against to get to state do not have that luxury. They go through cycles. Private schools like Grandview, St Alberts etc, do not.
I would say that has more to do with the history of the program, there's a reason Prince of Peace struggles even in a community with population to offer. But your point has validity, much like some of the small districts surrounding bigger communities as well.
