Sure.. but as I said, even if you accept that adding Clemson/FSU is worth enough to increase the SEC TV deal by at least another per-team amount.. then you've also established that the majority of the value in the ACC deal is gone (unless you, for some reason, don't think that FSU and Clemson were the main drivers of the current ACC contract value).It's not the teams alone. It's the matchups. More eyeballs. More Ad dollars.
Clemson vs. top half of SEC is worth X more $$$ than Clemson vs. top half of ACC. Same can be said for the bottom half. SEC is just deeper in football.
For the argument that the GOR could still be met, ESPN would then have to be willing pay the remaining 12 members considerably more than the value they'll get from that deal for about a decade. On the whole.. the value gain of Clemson or FSU making a lessor matchup valuable (say Clemson-BC), probably brings a higher profit margin than the added value from Clemson-Vanderbilt. Clemson - Alabama is a home run.. but enough to outweigh the losses from paying 12 other ACC members much more than their worth?
