[Husker] Armen Keteyian book on Husker football

[Omar Sharieff]

Has anyone read this book about Husker Football? http://www.amazon.com/Big-Red-Confidential-Nebraska-Football/dp/0809245809
I have a buddy who is a die hard USC fan and he's SUPER bitter about how hard the NCAA has come down on USC. So of course, he has to try to go after everybody else's program...including the Huskers.
Has anyone read this book? Is there any validity to the claims?
I need some ammo to respond....i would guess that if there was any violation that the NCAA would have looked into it. Since I"m not aware of Nebraska ever having been hit with NCAA sanctions, i'm guessing none of these were serious or every proven to be true?
I realize that this may be bringing up a dead horse that was beaten and buried years ago...just want to make sure i have my facts straight. Something about having Rose Colored glasses on i guess :-P
