My Dream Scenario:
Big 12 uses this leverage to redo the Tier 1 and 2 television contracts that pay more for the 10 schools and increases the contract for another 10 years (so like until 2035?). In that contract Fox and ESPN agree to increase $$ for schools that add market value only. The new contract now increases $ per year, per school...furthering its earnings gap from the PAC 12 conference. Once that contract has been completed, the Big 12 sends out an invite to UoA and ASU and expands to 12 teams. Tier 3 increase potential alone makes it palatable for the Arizona schools to make the jump.
