This is such a stupid idea it doesn't even pass the smell test.
1. As said above parents and kids are going to high school games. When high school ball is over it is later in the year and cold in big 10 country.
2. Friday nite at 7 pm or 6 pm does not give people time to leave work, get to the game, have some tailgating fun for the football game experience, so many people would have to take vacation time or whatever.
3. Friday nite would not compare to going to a saturday 11 am or 2:30 pm kickoff, beautiful day and weather, devote the whole day to your team, the late saturday PM and nite drive home.
4. Friday nite football bumps into what is usually "pick up" night at the local drinking places, yeah I am old but I still remember what friday nite was for.
5. I always like to leave Kinnick after a 11 AM start time and go with family or friends to a good eatery around Iowa City and watch some 2:30 games while having a nice meal.
What other good reasons are there that this is a bad idea.
