Someone from one of the papers needs to take this and crunch the hypotheticals versus if we'd stayed. On the surface it looks like we'd have been making 11-12 million a year more right now in the B12. If they keep pace with the B10 (full B12 share payed out just 1-2 million less than full B10 share last year I think) - it will take us decades to even out the 60 or 70 million gap we created with the switch, penalties and buy in.
Equity in the B10 Network adds ton of value too, though since it's not an asset that can really be sold I guess it's hard to quantify.
According to
Forbes.com, last year the Big XII paid out $22M per team. The article above said the other 11 B1G schools got $27M. The Big XII re-upped their TV deal in 2012. The B1G's current deal started in 2007.
The current Big XII deal is after the departure of several schools but the B1G deal is from before the latest additions. That obviously has some role to play but I think the Big XII's deal being five years newer and thus taking more advantage of skyrocketing rates would probably far surpass the fluctuating number of teams. Thus, my five minutes of Google research leads me to believe that the $5M difference is likely the smallest gap the two leagues will see for the foreseeable future.
There are too many variable to start guessing at "what might have been." Would Colorado and Missouri have stayed if Nebraska did? I doubt it. Would the B1G still have added anther team if Nebraska had stayed? Quite possibly Missouri so that answers both questions. I think it is extremely likely that the B1G would have added teams and the Big XII would have lost teams whether Nebraska moved or not. Nebraska's membership in a conference may have some incremental effect on the TV contracts but I would guess it would be dwarfed by the B1G and SEC having 14 teams while the Big XII has 10.
