to be changed to Saturday, (instead of Thursday), because BYU would have extra prep days for the Utah game. Given Utah's history of taking a BYE week or playing IAA teams the week prior to the BYU game-well it makes sense to me. Don't forget the MWC told BYU they could not have more revenue than other teams. They also denied BYU membership in other sports claiming full membership or none.
In turn they lured BSU with the lions share of revenue, and, let Hawaii in as football only while other sports compete in the Big West Conference. The games against PAC and MWC teams are decided on financial reasons that both sides can benefit from. However, conference heads can influence some decisions that are intended to give them an PR advantage over BYU (or other schools).
