The correction gets you closer but I do not believe your numbers are accurate yet.
ESPN already had the rights to all games controlled by the ACC, which I believe means all games hosted by ACC teams. This means ESPN already had the rights to all the games that were going to be OOC but will instead be conference games now because the football and basketball schedules expanded. Since the majority of OOC games for basketball and football are played at home, the rights for most of these OOC games will remain unaffected.
I agree that this deal is not as good as what the SEC, Big 10 or even what the Pac 10 got. The ACC doesn't get the results those conferences have gotten on the football field either.
Here are some numbers on TV revenue. The ACC is at or near the bottom of the list but there is no comparison with where it stands with the leagues below it. It will be interesting to see what the Big East gets with the new contract. I think it will be in the $11 million range ESPN offered last summer (football schools).
