I agree, but part of Giles slip aside from talent lows is the damage the wing does to it's own team (it's own defense.) Misdirection run offenses can be successful, but they do better when the majority of teams they play are run heavy. In Far SWVA, those Class 1 and 2 schools are far more wide open than the majority of the rest of VA in Class 1 and 2. That hurts a team like Giles because years ago, they just had to prepare defensively in practice for the upcoming opponent who was going to also run the ball the majority of the time. Nowadays, the football is often in the air and Giles can't really replicate this in practice.
If you are a small school where most of your starters on O (especially your athletes) are also playing defense, you are left to taking your 2nd team or JV offense (who only knows single wing) to try to replicate a spread or pass happy offense to prepare for the next opponent and that's hard to do. The single wing still fools people because they don't see it every game and gives a team like Giles an advantage, but it causes a disadvantage to Giles more than it helps in the modern era because of the inability in practice to prepare defensively for that upcoming spread offense opponent.
