BYU/ESPN TV Deal = $5-10 mil/year

If BYU goes to BIG 12

BIG 12 teams get around $20 mil/year from ESPN/FOX

If BIG 12 adds non BYU team we'll say UCF

$ 10 mil from ESPN + 10 from FOX goes to UCF

If BIG 12 adds BYU

$10 mil-($5-10 mil) from ESPN + $10 mil from FOX goes to BYU

So as you can see ESPN gets a $5-10 mil discount if BIG 12 adds BYU. This fact alone should put a lot of pressure on ESPN to get BYU into the BIG 12 because the are trying to grow revenue stream (better teams into Provo) but minimize costs.
