It's safe to say the ESL enjoys several advantages in regards to football:
1) the greatest amount of talent in Illinois football (certainly 6A and below) based on college scholarship offers/signees/NFL players, etc.,
2) their HC is also their AD, this is huge if you understand scheduling, resources, etc.,
3) Nike Sponsorship (this is a true sponsorship, 100% free/reduced lunch program but 4 helmets, travel gear, top of the line jersey's, etc.),
4) ESPN endorsement to fly to big away games, which ESL uses as a selling point to lure 'recruits' out of St. Louis and rival schools,
5) incredible facilities,
With these massive, and I mean MASSIVE, advantages, ESL has won 4 state titles since the amazing run of Coach Shannon in the 70's/80's/90's, and two runner-ups. That, in itself, is impressive....now let's compare to some public schools that offer none of those advantages, like PR (3 state titles and 2 runner-ups) and CG (4 state titles and 2 runner-ups).
I understand the amount of love ESL gets, and most of it is warranted, but it's easy to see why one could say they are a massive underachiever.
