The logic below is predicated on the Big 12 expanding with or without BYU, and based upon your numbers. Any error in the numbers is your mistake, Six Foot Seven, since I am too lazy to research correct figures. That said, here's where the argument is logically flawed.

WITHOUT BYU as one of two B12 expansion teams, the B12 TV contract increases by $40 Million. ESPN is still on the hook for $8 Million with their contract with BYU. 40 + 8 = 48.

WITH BYU as one of two B12 expansion teams, the B12 TV contract still increases by $40 Million. The difference here is that ESPN is no longer paying an additional $8 Million to an independent BYU for their contract. 40 - 8 = 32. What people aren't realizing is it's not just a difference of $8M, but really it's a difference of $16M (48 - 32 = 16).

Can you call that "savings"? Can you call it "cheaper for ESPN"? I guess it's a matter of semantics. One thing that is inarguable is that there's always money in the banana stand.
