If that were the case, why don't they go to ACC or Big XII matchups more often than B1G matchups?
Because those aren't equal scenarios, IMO. The SEC bias isn't insidious, it is BECAUSE of eyeballs and their financial interest. They aren't being blindly loyal and they aren't out to get the Big Ten ... it's more that they would actually be stupid to have two equally lucrative games to choose from and NOT to pick the SEC one over the Big Ten one. If the Big Ten one is simply the better ratings choice, they will obviously pick it.
However, that differs A LOT from how Gameday functioned in the classic era people are having trouble letting go of, if you ask me. ESPN used to have TV rights to Big Ten games ... they were truly picking the most exciting location for Gameday every single week; there was less tying ESPN specifically to the SEC, and the only difference between the SEC and ACC/Big XII in this scenario is that the SEC games are just better ratings opportunities on paper, too.
I feel many of us are talking past each other, though. I am not disputing that ESPN will take Gameday to a Big Ten location if it's the best option out there; they have literally done that on multiple occasions, including just last season. What I'm saying is that we aren't going to win any "coin flip" scenarios with games from conferences where ESPN is a LITERAL investor, haha. Let's pick our USC (Week 5) and OSU (Week 7) home games as examples. These would currently be the most attractive opportunities for College Gameday those weeks:
WEEK 5
#4 Oregon at #2 Penn State
#19 Alabama at #6 Georgia
#3 LSU at #17 Ole Miss
#24 Auburn at #16 Texas A&M
USC at #9 Illinois
#1 Ohio State at Washington
#8 Notre Dame at Arkansas
WEEK 7
#1 Ohio State at #9 Illinois
#13 Oklahoma vs. #7 Texas (Dallas, TX)
#11 South Carolina at #3 LSU
#6 Georgia at #24 Auburn
#19 Alabama at #25 Missouri
#22 Indiana at #4 Oregon
If we are undefeated going into those home games (especially the OSU one), we would obviously have a great case for getting CGD to Champaign. However, wouldn't Alabama/Georgia, LSU/Ole Miss, Auburn/Texas A&M, Georgia/Auburn, South Carolina/LSU and
especially Texas/Oklahoma also have great cases? My only argument here is that a Big Ten matchup has to be head-and-shoulders better for ESPN for them to head there, because they will NOT be broadcasting the game, period ... the Big Ten game will be on FOX, CBS or NBC, no matter what. So could they want to go to Oregon/PSU or OSU/Illinois?? Of course! Those are exciting games. But will ESPN want to go set their stage up next to Big Noon Kickoff for a game they won't broadcast instead of go to a super-hyped Red River Rivalry Game that is going to be on their premier channel, ABC? I think they'd have to be so convinced that OSU/Illinois is a can't miss stop, otherwise why wouldn't they go promote the conference they have literally, unambiguously backed financially?
