Miles is as good as the coaches he hires
on occasion there have been some disciplinary issues
About the same as you see on other teams.
Honestly I don't really care about Miles and how good a family man he is.
I care to the extent that it shows he is less likely to be in trouble himself aka Petrino or a few others.
He gets paid to win championships.
Among many other things. He gets paid to do what his contract specifies, which includes things like revenue, bowl appearances, player graduation rates (yes, that's in there), so on and so forth.
