@billmac91 can probably speak to this better than I, but in my IMO they've put all their eggs in the SEC and ACC (mostly just Clemson, let's be real) and they're slowly realizing, despite all their attempts to hype, not enough people give a shit about SEC and ACC football. Which is to say, People from Maine to Seattle to Austin, up to say Kansas, all through the midwest, and back up to Maine...some 75% of the country don't fucking care about SEC/ACC football. Because, as anyone who's ever had the "my conference is better than your conference" argument eventually comes to realize is - college football is regional. It's in the bones of the product. And, of course, this makes sense.. It's being
regional is actually an expansion of what it truly is... It's MY SCHOOL, or my state's flagship school, that I care about.
As an aside, I had this discussion with a friend who moved to Georgia and he was all upset when the B1G teams were getting waxed in bowl games and he said he'd have to listen to all the bullshit from his new friends down there. I said, "Why?" He said because Purdue is getting its ass handed to them by (whoever they were playing) and I said, "Sure... but why do you give a good god damn what Purdue is doing?" and he says, "They're in the B1G" and I said "Well, sure. I obviously know that. But, you know what? I'm not a fan of the B1G. I'm a fan of Ohio State. Tell you what, the next time you watch a game with your friends and a SEC chant breaks out, ask them if they ever chant NFC South! NFC South! When they say, well, no, of course not, ask them why they would give a rats ass about the SEC so much so that they'll chant SEC even when their own team just got pantsed by Alabama.
Anyway... all that to say this... the model they've decided on wasn't viable. There aren't enough eyeballs on SEC/ACC football and rather than try and play nice, they decided to go even a step further and actively alienate fans of other schools in other conferences. And, lets face it.. even as it is, they're not pumping up Vandy or Kentucky, etc.. It's Alabama and Clemson with a supporting cast of Georgia and Florida, along with LSU and and Aggie (which.. if you need evidence they're trying too hard, Aggie is it) They got a boost with the ACC's footsie with NoD this year, but even that isn't enough eyeballs.. because NoD fans aren't going to suddenly start giving a shit about Wake Forest or North Carolina games. ESPN needs the eyeballs our fanbase brings to stay afloat.
