The problem is that the ACC just finalized their deal with ESPN and it won't be renegotiated for several years. Second, what people have to understand is that the contracts are based on who are members of the conference. Notre Dame and Texas won't even be members in football under this scenario, and half of the games they play every year against ACC schools will belong to other networks.
What has to be taken into account is that non-conference games are not really valued as part of TV contracts. When networks negotiate with conference, they're paying for conference games with the right of first refusal for non-conference games. However, the non-conference games are paid as a separate, stand-alone event. So when you hear, for instance, Duke basketball being set up with someone in New Jersey as a "TV game," what that means is that ESPN separately negotiated that deal as a standalone payout separate of their broadcasting rights with the ACC. This is because Duke's non-conference games were not technically part of the television agreement.
So when the ACC tries to renegotiate its deal with ESPN, which again won't be for a while, it's not gaining much leverage by having Texas and Notre Dame being affiliate members. The truth is, whereas each fully-fledged member would create four new football games, as part of the contract itself, this situation would create zero. Because again, the non-conference games are paid separately when they happen. The reason for this is that networks, when they negotiate, cannot know what non-conference schedules are going to look like. So it pays for the value of conference members, then retains the rights of first refusal when the non-conference games come about. The value of non-conference games are often less than conference games, even when they match two big-name opponents.
