FWIW:
Smith was a professor at Penn State from 1968 to 1996. He's "professor emeritus" now, but it's questionable just "how close" to things he may have been during the ensuing 19 years.
A legitimate question is: Where was this guy and why was he not speaking up prior to NOW? Seriously, I've never even heard of him prior to today, and a Google search on his name indicates that while he has been quoted a few times during the 2011-2015 period, he hasn't been heard from overly much.
One of the articles where he is quoted is from 17-November-2011. There are definite hints that, for whatever reasons, he didn't like Joe Paterno at the time. References to him as a bully.

Interestingly, ANOTHER article in which he is quoted is in a Centre Daily Times (State College newspaper) editorial on 2-July-2014. One of the major arguments he is making in that article is that the NCAA was full of bull-kaka in terms of not affording Penn State due process in July 2012. That's not a popular opinion among many people --- including the majority of folk on this message board. But I intuitively like people who are smart enough to see that BOTH (a) Penn State coaches and administrators screwed up AND (b) the NCAA should be totally ashamed and embarrased about the process in which they went about administering punishment. (PSU deserved "due process" but everyone was content to just sit back and say "fuck them").

Also: for much of the 1980s, Smith served on internal committees at Penn State that oversaw Penn State athletics. I'm sure he'll talk about that era as part of his book. But if Penn State was a "rogue program" during the time he was there, what did he do about it then? Doesn't/didn't he have some responsibility himself to do or say something if he knew something?
Anyway: some context to this author and some thoughts to consider. We'll see what the book says.
