Some quick stats that
have zero scientific value...
Iowa vs. Iowa State all time score
1,394 - 818, 42-22 record
Hayden Fry era, 20 games
655 - 299, 16-4 record
32.75 PPG
Average MOV, 25.00
Kirk Ferentz era, 18 Games
420 - 309, 9-9 record
21.00 PPG
Average MOV, 18.56
Like I said there is obviously no analysis behind these numbers but one could at least start the conversation that Hayden Fry kept his foot on the gas full time and Kirk doesn't. His average MOV was over 6 points higher than Kirk's. That to me isn't explainable by Iowa State maybe having worse teams than they do now; 38 years is a lot of seasons to sample from.
Even worse to look at, during the Ferentz era's 9 losses, 7 of them were by less than 10 pts:
'99 - 7 pts
'01 - 3 pts
'02 - 5 pts
'07 - 2 pts
'11 - 3 pts
'12 - 3 pts
'14 - 3 pts
One could say that's good because we didn't get stomped, but I'd also argue that if they were that close we had a better shot to win those.
I'm not claiming that Ferentz lost games to ISU because he wasn't trying to score...that'd be absurd. And it's also only stats from Iowa vs ISU...I'm way too lazy to do this against the rest of the B1G. But when you look at the two coaches side by side it's hard to argue that Fry's aggressiveness didn't help him win ballgames. Kirk should have learned the phrase, "If you don't like it, stop it" a long time ago.
