Hold on, educate me what players did we miss out on that were "good" football players because they wanted to go to a school with perceived harder academics? I'm not trying to be a wiseass, I just think the vast majority of football players at the FBS level are not looking for harder classes. I just don't see it.
Some kids will choose the Ivies over FBS. In the class of 2022, 4 kids UConn offered decided on Harvard, 1 Princeton, and 1 Brown. 2 PWO offered kids went to Columbia and Brown.
When it comes to FBS football, I would think most kids are not choosing schools based on academics, but on coaches, relationships, playing time opportunities, proximity to home, ability to develop football talent, facilities, schedule, prestige, winning,... and now NIL opportunities.
