No I don't, because they are also getting paid.
There are certainly going to be instances where a guy takes less because he has a better relationship with a certain staff, and that relationship certainly could have started in high school, but this is a 100% business now. Guys are looking for PT, money, and wins.
And even if you believed laying the ground work in high school will pay off, how in the world would you know which guys to work on. I never heard of Justin Harmon, Marcus Hill, Dante Maddox, Marcus Domask, etc.
As chance may have it, I actually had some random dude strike up a conversation with me in the grocery store. He was wearing an Iowa hat and noticed my Illini hat. He really only said, I like Terrence Shannon and I hate this transfer $h!t. It's just a different game now, and many don't like it. I think those that win will rather quickly get over it, but those that don't, interest will wane.
