There's a difference between getting 3 teams (21%), 4 teams (29%), and 5 teams (36%) in the playoffs and the 29% is only set til 2028
How wouldn't FSU/Clem help the BIG?
Reasons:
School: More money like any other school (OU, Tex, USC, UCLA, Ore, UW and all the teams who voted to add competition)
Fans: Better games throughout the season
Making the playoffs is irrelevant if you're not winning it all
You just don't want to admit you got screwed by the lack of participation in the distribution. Trust me, I wanted that ... it would have meant more money for the SEC. But the differences you point out were considered when they decided on the 29%. See my other post, where I list what a CFP-12 would have been. Both leagues will be fine with the teams they have, and if the ACC collapses they will get bigger shares anyway.
The B1G is getting the largest TV money, and the largest CFP amount already without you. Why would they want or need you? They have PSU, tOSU, UM, UW, UI, USC, UO, and UW. They will always have the 3-5 they need to keep their 29%. Adding you will do the same with SEC - give mid to low teams losses, and take away per team money. Why would they do that?
As for the 2028 re-evaluate, that doesn't help you right now. The SEC and the B1G would want nothing more than to not have to deal with FSU and Clemson right now. They are both totally fine, and both teams bring more trouble than they are worth. Once the ACC breaks up in 2036, or a little before, then they can evaluate that in light of the revenue realities at that time.
All those teams got added before the TV contracts were signed. You might get added the next TV contract, but you guys are trying to get out now. Unless TV would add pro rata shares it won't happen in the SEC. In the B1G it won't happen for full shares because UO and UW aren't going to allow that. And, as I said, adding you won't add more teams to the CFP ... just switch up the mix of teams that will get in. They don't care if it's Wisconsin or FSU, or Oregon or Clemson. They'll easily justify their 29%.
The teams did vote for the new schools to come in. But in the B1G they did for USC and UCLA only because of pro rateashares provided by TV, and then partial shares for UO and UW. OU and TX were no brainers for the SEC - two bluebloods, and to keep them from going to the B1G. But, now you have no to limited CFP value, and the mid to lower teams in both leagues are tired of adding teams that make it less likely they will ever win a CC, or get to the CFP. You have to see that, right? Ole Miss isn't going to vote you guys in. USjr and UF aren't. Vandy, Mizzou, Arky, MSU, Auburn have no desire to have you in the ACC and make their path more difficult.
I agree that it would add more great games. But the SEC is already chock full of them once we go to a 9 game IC schedule.
You have to make the CFP before you can win it all. Yo would think that you would get that. The years you beat Bama, you likely wouldn't have been in at all if you had been in the SEC.
