all over the place, including in the Dodd article cited on CB today. He's comparing apples to oranges, presumably intentionally, because he's a B12 homer.
I am speculating that the deals will be close based primarily on 1) the current deals are close now and both conferences lost two of their biggest media darlings (although the B12's were more significant losses than the P12's in terms of viewership), and 2) the fact that numerous analyses that have been posted here and elsewhere over the past few months show that the B12 and P12 are pretty close in terms of viewership and value. Some show the P12 with a slight lead, some show the B12 with a slight lead, but there's no analysis out there that would support a $20M difference.
