I've thought about that and I think it's a combination of a few things. I can admit that Brian is probably not the best as an OC and was a bad decision. I think KF's style has ran its course finally. I also admit that maybe Iowa should evolve to a more current offensive gameplan/style. In the past, I've always stated they run a complex NFL style. We have always heard coaches and opposing players describe playing Iowa as "We know what they are going to do". "They are so well coached and prepared and do what they do well". Well, we used to take that as a compliment, but, I think over time teams really do have an advantage on defense now as Iowa has been doing it for decades. It's not a compliment anymore, it's a liability. Now they are reading the snap counts and defenders are always in positions it seems.
I just think Iowa is "Type-cast" at this point. Unfortunately, this is what KF is comfortable with and likes to coach. I think you now throw the portal and NIL into the equation affection recruiting and player attrition and that is an issue. Iowa was always a developmental program where they put time into players. Now, there is free agency in college for the most part. Is Iowa going to have the time it needs to develop players or will the players leave always affecting Iowa's depth and leaving holes at certain positions.
If KF wants to continue to lead this team and program, I think he needs to do what John Beilein did at Michigan in basketball. Michigan was struggling horribly at defense for a couple years and it was holding the team back. John found a defensive coach and completely gave him the keys to the defense and he got the hell out of it and let the coach do his thing. I think that is what KF needs to do. Find a proven or up and coming coach and hand him the keys and stay the hell out of it. Obviously, he needs to have some part or say for complimentary football for the defense, but stay out of the design and playcalling and let the OC do what they are good at. I think this is the solution and only way for KF at Iowa.
