This is actually one of the better realignment threads I've seen here, and I'll add my $0.02 worth.
Yep, it's all about money. The B1G doesn't NEED to expand. But the wild card in all of this is Fox. Because of their relationship with the B10, I can see a path where they would want to add to the conference to help build the overall value and could put their thumb on the scale. If they deem it a worthwhile long term investment, It could certainly happen...especially if a school like ISU will accept a revenue share for the first decade that is 50-60% of what the new TV deal is. This to me seems plausible because their relationship owning half of the B1G network kind of gives them a protective moat and a reason to want to enhance the brand beyond what it currently is. If streaming is where it's at 10 years from now, it would be good for them to lock down schools when they can get them.
As for those ******* at ESPN, even though 8 schools just got crapped on, there is no reason not to believe they don't have a long term plan to build the AAC brand into a solid Tier 1 league. We know how they can hype up games to drive viewership. Their goal was to get it on the cheap with Big12 eyeballs to help grow it.
Point being in all of this, I think Fox is going to be the ultimate king maker and decide whether the Big 12 stays together or the B1G/PAC 12 expands. Even though the remaining pieces on the chess board are not as valuable as OU and UT, they still have value. Like Campbell said, keep winning and everything takes care of itself.
ESPN also has a lot of motivation though....
Overall, the B12 pays out about $400M per year. These were about to be renegotiated and would have increased since these deals were signed almost 10 yrs ago. So, the value is UNDERSTATED at $400M/yr. Over the next 4 yrs that is ~$1.6B+ in league value. This is split between ESPN and Fox.
Bowlsby estimated that 50% of the value came from tx/ou. So, let's use that number... roughly $200M/Yr in value for tx.ou in the B12. ESPN wants them in the sec to consolidate brands further and create more value to the inventory (tx vs. tamu, ou vs. bama, tx vs. uga, etc.). So, how much does that add to the value? I don't know... I would say the value is probably at least between $250M-$300M (remember the $400M was about to increase in the next round of media deals and does not include ~$15M/yr in rev OU, Tx get from their school networks that now go to espn on the sec network). It will only cost espn about $120M/yr (payout is expected to be ~$60M/yr for each). So I would guess that is AT LEAST somewhere between $130M - $180M in value to ESPN ($300M - $120M = $180M).
However, if the B12 does not dissolve, the benefit is delayed and they also must continue to pay out the remaining years on the contract. So, ESPN wants to end the league asap. Ideally, everyone is moved to the aac and you pay the schools ~$10M each vs. $25M ($200M/8 = $25M, saving another $15M per school). But B8 were not interested in that. So, now you need to get life rafts for at least 4 more schools in order to end the conf...
Some options below. Net is, ESPN would need to make the other leagues whole if they were going to add teams. So, ESPN could offer deals that would make the other P4 conference members whole (pay as much to new teams as they distribute to current teams)
ISU/KU to b10: Cost +$25M per school,
$50M/yr ($50M b10 conf pay - $25M B12 estimated pay after 50% of B12 value is split 8 ways)
WVU to ACC: Cost
$10M/yr (roughly $35M in ACC - $25M/yr B12)
TT/OSU to PAC: Cost +$10M/school, or about
$30M/yr (roughly $35M in PAC - $25M/yr B12)
Others: Savings of $15M/school or savings of
$45M/yr ($25M B12 vs. $10M AAC)
So, very rough numbers... for about
$35M-$45M /yr in cost they can dissolve the B12 and cash in on the SEC investment worth upward of
$180M/yr. So, over the next 4 yrs that could be about
$500M.
These are just estimates based on the numbers reported by conferences... this is not intended to be exact but to illustrate that ESPN has a lot of value they believe is coming their way. They want to cash in now. They are motivated to move quickly and it likely would not cost them a lot to do so. Lowest cost option? Get enough teams in the B12 new homes so the league can be dissolved.
