As a 31 year old, I don't have a huge problem with the 11 am kickoffs. I'm up early anyway, so getting out to the tailgate by 7 is not an issue, plus I get back home at a decent hour. The heat for those early season 11 am games is brutal, but not so bad later in the year.
My issue with the 11 am kickoffs is how it affects the student atmosphere. Students are not going to get up early, and they have been a huge factor in our home field advantage the last few years, plus the tailgating scene.
