The B12 has performed really well on $/team payouts.
Over the next 5 yrs or so, it will be important to monitor the years where the Sugar Bowl is a playoff game (pac 12 impacted by the rose bowl this year) and also the revenue from the new ESPN+ deal that included adding three more B12 title games to ESPN/ ABC. The details on this deal were not made available when it was announced.
The last time the Sugar Bowl (2017/18) was part of the playoff it coincided with first year of the B12 title game. Since both the B12 Title Game and the Sugar Bowl account for $3-$4M per school, adding the title game offset the lost Sugar Bowl Revenue. The ~39M per school this year includes both the B12 title game revenue and the Sugar Bowl revenue. I believe there are revenue increases baked into the current deals that will help offset the lost Sugar Bowl revenue that happens every 3 years, but may see a year to year decline in 2020/21 (2 years from now) vs. 2019/20 (this year). However, the new ESPN+ deal goes into full effect in 2020/21 which coincides with the lost Sugar Bowl revenue...
So, net is, conference revenues are on an upward trajectory; continued success making the CF Playoff and NCAA Tournaments will continue to boost our conf payouts; conference TV contracts have built in increases over the next several years that should increase the payouts further; and finally, the conference continues to look for new revenue opportunities (B12 Title Game, ESPN+, etc.)... All good news and currently a solid #3 in terms of overall conference performance. Meanwhile, Texas, OU bring in revenue equal to or greater than SEC, B10 once you factor in the LHN and OU's Fox Sports revenues for T3 rights.
