BYU WON'T shouldn't spend Church funds on athletics. There are some very well-off donors who have stepped up in the past to help underwrite changes that needed to be made. If those donors feel that an influx of funds will make changes that they see as being needed then it will happen.
I don't think that Ty is going to be let go. I think that Cahoon is gone and probably Mahe. Empey should stay....the OLine has been decent most of the year and has shown improvement year over year for the first time in 10 years.
Ultimately, the folks with serious resources who are invested(emotionally) in BYU football are the ones who will be able to effect serious change.
