I wonder sometimes how a guy like Paterno would handle all of the changes we've seen (even since Franklin took the reins). NIL, portal, playoffs...my suspicion is that Paterno would have retired had all that transpired under his watch. Even Saban quit Alabama, he'd had enough.
Ultimately, I think Franklin was a nice guy, good ambassador for the university, which was needed after the Sandusky mess. Franklin thrived under that, with the management that hired him and that he worked for, and managed to build an impressive "body of work." In this day and age, though, that's obviously not enough if your AD has it in his head that "we're winning a NC this year." Franklin just couldn't make it happen...and I think Kraft knew that.
