I'm not sure if, with this message, you are agreeing or disagreeing with my post. Either way, I agree with what you have written here.
In my post, I referred to the star system and college recruiting as a measure of talent (natural athletic ability), not as a measure of overall high school football playing ability. Football playing ability can also be developed through training (weights and conditioning) and practice. When, as you put it, players are "judged based on their potential and measurables," it is their talent level that is being judged.
It is my contention, which is just one man's opinion, that as a program East St. Louis's teams generally have more talent than Cary-Grove's teams. The overall skill level is very similar in my view, though the style of play is (of course) very different.
