I guess I disagree with that a bit.
There are a handful of programs that are of national interest irrespective of on-the-field performance. Texas falls into that group. So does Notre Dame. Michigan, Ohio State, USC, . . . I don't know--maybe Alabama. But those programs are pretty limited in number.
And then there are a lot of programs that are of national interest when they're good enough to be challenging for a national championship. I think Clemson is the archetype for this category. Clemson is obviously of national interest right now. Pretty much all of us watched them get their clocks cleaned by Duke Monday night. But pretty much all of us remember pre-Dabo Clemson, when that program wasn't particularly good. And when it's not challenging for a national championship, Clemson is of little interest outside the Greenville-Spartanburg-Anderson megalopolis.
. . . and actually that point is why I'm a bit skeptical when people act like its just a done deal that Florida State, Clemson, and UNC are all leaving the ACC in 7 or 12 or 14 years (depending on the GOR situation, which seems really murky). I mean, Florida State--ok. They may be in that top group of programs that are of national interest regardless. But Clemson and UNC?
The SEC and B1G have enough members right now that they don't need expansion. They can expand, but they don't need to. So if they're going to expand, those new teams need to bring in more in additional revenue than their cut would be. They need to expand the pie bigger than the slice they're taking.
And I really don't understand the argument for how UNC does that. UNC football is of no real interest to anybody, even in North Carolina. UNC is all about basketball. But a lot of UNC's appeal in basketball is about its rivalries (particularly with Duke). Take away those ACC rivalries, and does anybody care about UNC regular-season basketball?
Which brings us back to Clemson. Yeah, Clemson is a property now. But Clemson wasn't a property 15 years ago, when they went 7-6 and lost to Nebraska in the Gator Bowl--a result that was pretty par-for-the-course for Clemson pre-Dabo. And one wonders whether Clemson will be a property 15 years from now, with every other program in college football paying players and Clemson's on-the-field results consequently flagging.
At least, that's what the SEC and the B1G will be wondering.
