All I know is that whole process is going to be quite interesting. I still don't think Kirk is gone for another 5 years or so. At that point, will Brian have accrued enough experience to move up? Some fans will say yes, some will say no. Obviously a lot will depend upon the trajectory of the program as a whole at that time, and the results under Brian's offense.
Nepotism aside, it would be nice to find a replacement that has a connection to the program, or is vested in Iowa in some fashion. The last thing I would want to see is a good young coach come in and use Iowa as a stepping stone, which Campbell and Brohm both are going to do. Brian would at least fit that mold.
Another name to at list think about is David Raih, former Iowa QB, currently building up quite a resume in the NFL as an assistant. Would he at least be interested? I don't know. The negative there is that he has very little recruiting experience, but, that's why you put together a staff that does.
At the end of the day, I just want to have a successful program.
