Franklin's challenge is to prove he can do it without Joe Moorehead:
Without: 20-15 (0.571); 14-12, before; 6-3, after
With: 22-5 (0.815)
That's a wee ugly. Now, I think it's fair (moreso logically than practically) to question whether Moorehead made Franklin or vice versa. As if Franklin was ramping up to go roughly 22-5 (2016-17) no matter what, and we're over-interpreting the Moorehead correlation as a Moorehead cause. Who am I to call that technically plausible thing absolutely impossible?
However, given (1) Moorehead's preceding reputation, (2) Franklin's in-game confusion in all seasons and even the observation that, perhaps, (3) had BO'B stayed, he had PSU on a steeper trajectory than the 7-6s that JF accomplished in the pre-JMo years, I'd be skeptical and not bet the house on JF if I were PSU.
