I am not a fan of games between any FBS and FCS teams. They should each play in their division.
Having said that, BYU has a large fan base, and the game will be much more broadly available than many other games this week. Further, it will continue to be available on demand. Thus, because it has meaning to BYU fans and is widely available, I am sure there are other games this week that will be much more meaningless, including games between teams who have been eliminated from their conference races or bowl eligibility.
Go Cougs!!!!!
