That is, in fact, a good and logical reason for them not doing so.
Why do you think teams don't?
Oh, I don't know, because they already have more than enough exposure?
The reason is simple. We aren't trying hard enough to schedule those teams. The schedule we have now is what KF and Barta want. Do you actually think that Barta has called Alabama? Or any of the schools I have listed?
We are scheduling these teams well in advance. UNI is scheduled for 2018. We have a game scheduled Miami OH and Northern Illinois in 2019 and 2020 respectively.
Don't sit there and tell me that we are trying to schedule better games, when everything they are doing tells us they aren't.
