Colorado State didn't ask to continue a home and home series with Colorado. CSU understands they are in a lower conference, less prestigious, and that they need to take what they can get. So they agreed to play 20 minutes from CU, in what amounts to a home game for the buffs. Then realize they can't get CU to play in Ft. Collins anymore.
BYU doesn't know its place. They think they are worthy of a home and home. When BYU wants to do 2:1 with Utah, then the game will continue.
