Only 8 months after it was formed, the Pac-12-Big Ten partnership has been dissolved. "The two leagues announced Friday that their pact, which initially called for 12 football games per year, has been called off. The reason: at least four Pac-12 schools were unwilling to agree to mandatory scheduling, ESPN.com has learned. A key sticking point is that Pac-12 teams play nine conference games, while Big Ten teams play only eight. Adding in traditional non-league series like USC-Notre Dame, Stanford-Notre Dame and Utah-BYU, and it makes the scheduling situation tougher for those in the Pac-12. " That's a shame. It would have been fun to build some cross-conference rivalries with our Rose Bowl partner.
