My honest opinion...big sports media has a major northeast coast bias, and that at least played some role in PSU being treated with kid gloves, almost like the media was rooting for Penn St to be able to successfully move on from the Sandusky mess. Think they would have been pulling for us under those circumstances? I sure don’t.
I also think the scandal happening at Vanderbilt (old money + academic elite = respectable) made it easy for some to see it as an exception to rule at that university whereas at a public university it might have been perceived differently.
So Franklin probably benefited from a mix of regional bias and class bias. That may not account for it 100%, but I bet it didn’t hurt.
