There should be some kind of enrollment vs CB ratio. If your CB is almost equal to your enrollment you are a football factory
If you look at CB ratios it should not come as a shock that St. Ed, X, Hoban, and TCC literally leap off the page in D1/D2. So to your point yes with the right CB, actual enrollment doesn't matter. Hell TCC only has 219 boys total, and is easily a top 5 D1.
