Yeah but ESPN is trying to make Clemson, North Carolina, Florida State more money so that they don't bolt to the Big 10, where ESPN doesn't have an agreement. This is a way to do it without themselves paying these schools.
Revenue of the ACCN is split 50-50 with ACC and ESPN. If they merge, the ACCN replaces the PAC Network. ESPN would invoke a clause in their contract or renegotiate with Comcast, Cox, or whoever is out in the West Coast for in-footprint subscriber fee, which would be something like 4 times more than out-of-footprint. Thus, more money to ESPN and more money to the schools.
