If we assume, all of them are offered money by all of the schools then even in that scenario surely there's gotta be that separates one from the other and it can't just be a bidding war or else every school with deep pockets would get the recruits they throw most money at.
Texas is the richest school in the country, football is their religion and they're probably as desperate as they've ever been. That means purely based on financial resources they should have the #1 class pretty much but in reality they ended up at #11 or something.
Recruiting is shady as hell but it's rarely just about money changing hands. It's usually about connections as much as it is about on-the-ground tactics and the simple ability to sell and close.
Curtis Blackwell has an important job on MSU's staff. The man has never coached college football and his official role is Director of College Advancement & Performance at MSU. He has been an assistant at the HS level in Detroit but most notably prior to this job he was the director of a football academy in Detroit which 'guided' HS players in their pursuit of a football scholarship. In other words, the man is about as 'insider' as you can get on Detroit HS football and that's the only reason he works for MSU. How much dirty stuff happens at that nexus between high school and college sports, how much does he know or partake in? Who knows, but what we do know is that he is exceptionally well-connected.
And of course, Chris Partridge is at Michigan because he was the HC of a New Jersey powerhouse HS program and helps Michigan big-time in being a dominant force in New Jersey recruiting. There's a reason Michigan got 5 of the top 10 players in the state this year including the big prize, Rashan Gary (who of course played for the school Partridge previously coached at). Again, I'm not saying anything about money or the absence of it, I'm saying it's the connections that usually matter most in the end.
