If you’re a football fan, read Bill Polian’s book.
He talks about Manning’s NFL combine interview (scheduled for 15 minutes).
Manning shows up with a huge binder full of questions, discussion goes on for 3 hrs plus.
I remember the first time I went to Denver about twenty years ago, Elway owned half the car dealerships in town. Manning has talked about how Elway is a mentor to him and I don't think he meant football.
