All indications is that FSU would receive a full share especially because the Big10 wants them. They likely command a higher share than Wash and Oregon. Probably not like USC, but USC came with UCLA too...
FSU is not as valuable to the SEC as they are to the B10. But people have been saying that the SEC has a pro-rata clause that allows them to bring in a team(s) at a full share. I can't believe they can bring any team, but who knows.
If the SEC can auto bring anyone and the B10 doesn't offer FSU a full share, I can see SEC playing defense. Who knows what the SEC is thinking, but it appears to be UNC + another. Also FSU wouldn't be spending all this money and willing to pay 200M+ to go get paid 50M somewhere else. Either they are a headless chicken running around or they already know what the SEC and B10 are offering
