Old Joe has always been one of my favorite coaches as I've never read of a breath of scandal about his team or any of its' players. His character is on a par with that of the Duke, a trait that is rare in big-time college football.
The school did have it's issues about 11 years ago when they had losing seasons for about 3 years. They thought Joe Pa has lost the ability to coach. Little did they known.
He let a few players play who had gotten into trouble. It changed the face of the team and took about 3 good recruiting classes to get the bad attitude out of them.
Since then they have been playing Joe Pa football as usual.
