Even being 2-5 against Franklin I wouldn't say he's a better coach then Ferentz. Sure he wins the head to head battle, but that should be a no brainer. PSU has much larger appeal nationwide and recruits better then Iowa does. KF is 12-28 vs. top 10 teams and that's not something to brag about, but how many of those games do you think we were favored? Flip the script to PSU's 4-21 and I'd venture to say that playing 15 less opponents I'd bet they were still favored in more of those games then we were.
I'm not saying KF is a better coach, but I bet if you put KF at PSU with his talent he'd be much better then 4-21 in those games and if Franklin couldn't do better then 4-21 with his rosters at PSU I'd venture to say that his numbers would look better at Iowa then they did in Happy Valley. Some programs simply recruit for themselves and as a result it distorts the perception of how good a coach they are while they're at those programs. I'm thinking Franklin falls into that category.
I mean, that's really my point. That's why 'better' was in air quotes.
Because it's the only theoretical way to easily quantifiably measure the two.
My actual point really, is that Ferentz is roughly .500 against PSU as a whole.
His record against Michigan was pretty good up until a few years ago.
Asking for more is impractical due to the reasons I could argue Ferentz is better.
If we try to get to apples-to-apples
On top of head to head, you'd have to do a whole math dive.
Post and prior to NIL
-money donated
-money spent by athletic department
-average NIL paid to player by position
-some value placed to historical wins and rankings
And my perennial favorite I like to talk about:
-The ratio of state population to D1/power 5 roster spots.
When teams (not in Florida, Texas, or South Bend) average up ~40% of in state players, I believe that is a huge factor. I think it falls right below money.
And it is why I believe Iowa punches far above it's weight class. And that Kirk Ferentz is historically exceptional at juggling all the things that work for him and the things that work against him. Certainly better than coaches with far more things working for them and fewer things working against them.
