This will be a fascinating watch in the coming years. Do the SEC and Big10 add even more teams (20 to 24) and eventually leave the NCAA in football and do a 16 team playoff with just the 2 conferences? Try and force ND to join. Could the big10 add a 10th conference game and cancel all games with ND? I'm sure there are so many moving parts behind the scenes with the conferences and tv networks we will never know about.
My gut has said all along I think there will be 3 major conferences in the long run but that may not be until 2035 or so.
SEC/B1G likely can't grow enough to pull it off with just 2 but 3 conferences of 20-24 teams would be a large enough swath to not alienate that many viewers. 60 might be iffy but 72 def carries the majority fans with them to Super League D1 or whatever they call it.
Some data scientists will know these actual numbers, but I'd guess somewhere around 64-68 you start to get penalized for every fan base you remove.
The Big 12/ACC/PAC arguments are because all three confs and their fan bases feel that heat.
We/They should all be mad at the SEC/B1G but that's not how it works of course.
One way it could work is to see B1G break the PAC by taking Oregon/Stanford/WAS and Notre Dame. That gets them to 20.
SEC then wants to match but also wants to be aggressive to get to that final number so they invite 6-8 ACC schools to apply.
B1G says hold up lil buddy and also expands with 2-4 ACC teams.
That total would break the ACC grant of rights via vote and mean cost them essentially zero.
Which gets them out of a cheap TV deal with ESPN.
This leaves Big 12 as 3rd man standing and they take the ACC stragglers and PAC pieces of value to get to 20-24 as well.
A distant 3rd conf but the one that stretches coast to coast with all 4 time zones worth of games to broadcast.
And the one likely stuck playing Thursday and Friday nights.
Long term all these confs have to start looking at time slots and streaming service buys.
They want to fill their major TV time slots for ad revenue (Tier 1 and 2) and ALSO
fan bases who will fork over 9.99 a month for their service(Tier 3/4) then pay a package fee (say 60 bucks) for their college football streams.
Of course you could see the PAC or ACC become that 3rd conference as well.
It just feels tougher to line that up logically, but I am also a Big 12 homer.
If ESPN wanted ot just toss the 15 years left on their ACC contract and massively increase it, you'd like the ACC's chance a heck of a lot more.
But I'm still not sure that would appease FSU/Clemson/UNC/VA who have to view SEC/B1G at a massive cut above any other option.
