Trust me when I say this. Fans have zero to do with Iowa football. There are about 30 boosters who control the fate of Iowa football coaches. Exactly zero of those people are members of this forum. A full fan revolt will never happen. It's just not.
I can understand that you want Iowa football to be a Lamborghini, but we are just more F150. Every blue moon we roll out with a platinum edition, but most years we are just XLT. I would not advise holding your breath waiting for some giant makeover, because I just don't believe it will happen.
P.S. I wonder what the fan bases of the 80% of the teams that Iowa routinely finishes better than would say Iowa's "problem" is. It seems like you are spoiled by years of above average results and are blinded by desire for bigger and better. If it wouldn't involve my own and Iowa's players pain and suffering, I kind of wish that you and all like minded fans got a few years dose of Nebraska's reality. They once believed that the mountain top was theirs. They also believed that they were 1 awesome coach away from regaining elite status. Don't look to hard at that green grass on the other side, because 1 day I fear that we all look back at these last 40 years and wish we could return to that.
