His thought have always been this.
The “real” classes for the most part weren’t much different in difficultly. The difference was, at MSU you could minimize the amount of those real classes you took in season and take the “blow off” classes that were automatic A’s that kept players eligible. Not to mention, allowed you to focus on football in season.
And if you weren’t there for school, there were majors available that keep almost anyone eligible.
So I wouldn’t be surprised if OSU had a high GPA. My guess is that is inflated by a lot of blow off classes and easy majors.
