I think the biggest cancers in the program were Doyle, Wallace, and BF. Doyle was gone immediately which was good. Wallace should've been gone immediately and probably Brian too.
That's my biggest gripe with KF in the whole thing. They decided to make an example out of only Doyle in hopes of it going away and for the most part it worked. That was enough for most people. I don't think KF was as guilty of being a racist as he was of being ignorant number one, and selling part of his soul to keep Wallace and BF around.
No one is perfect. I've said and thought plenty of things in my life that I shouldn't have. That can be fixed most times if someone reflects. I think KF probably did that. My problem is he didn't do enough to fix the program when it came to accountability in Wallace and Brian. Those were the only two other individuals that had complaints come out from players and those complaints were really, really bad. We know the reason Brian was kept on staff, and after Wallace became assistant HC we know why he was kept. He's the son KF never had.
It would be ignorant to think the KF was in the weight room directly hearing what Doyle was saying, how BF treated guys in practice, and heard/saw how Wallace treated players like Kallenberger. At the P4 level head coaches aren't in those places. If you think they are you're just flat wrong...it doesn't work that way. P4 head coaches are like CEOs of big companies...they're managing at a high level and assistant caches are like supervisors directly running departments and interacting with employees every day. I've personally talked to several former players just because I got to know them in high school sports where I live. My part of the state has a lot of Hawkeye football players past and present. Several of those players have told me in casual conversation that they hardly ever saw KF other than in whole team meetings and some never had a single one on one interaction with him other than in passing for 30 seconds.
All that said, when it came to light what happened all 3 of those guys should've been gone. That's on no one but KF. It's a black mark, IMO and it's why I rant on here about what I'll do if Wallace becomes HC. That's not hyperbole from me, I just couldn't be a fan at that point as the father of someone who struggled in the exact same way with the exact same disorder as Kallenberger. I shudder sometimes when I think of how I'd react if what happened came out as happening to my son, because I don't know if I'd have the self-control it would take to stay out of prison.
I think you can be a good person and at the same time make huge mistakes. KF came from an era where things like that were just "hard coaching," which isn't an excuse, but it at least has to be considered because everyone of us is a product of our upbringing and environment. But KF was very, very wrong in how he handled the whole thing and I don't think winning a certain number of games wipes it away.
