I think most coaches genuinely care about their kids and would do most anything to help them grow into men and be successful. There are exceptions, but I think most college football coaches are there because they love the sport and they love their kids.
Do I think KF is more special than most in this regard? Yes, I do. I am biased, but when you see that guy tear up in nearly every damn post game interview, you know he gives a shit about his kids and the program. He also is nothing but class to the media, refs, fans, etc. He is just a real dude.
The only real mark against him in his 25+ years is the racial stuff that came out involving Doyle and perhaps his dopey son. There were some former black players that spoke out against the culture of the program in that regard. But, in a very KF fashion, he showed humility, apologized, and made meaningful changes to his program. He is a good man. Period.
