Yes, ND does not have the clout with audiences it used to have, but that means what to you?
ND outside the BT is a major threat to the BT. Recent events should mark how and why. No matter how gigantic BT schools are, no matter that they get a totally crooked (as in he cares not a bit how many violent criminals play for him) HC like Meyer who wins the NC, outside the midwest most CFB fans care very little about the BT. The ones like me who hate the BT, do not have it in the way that makes us watch the hated thing. Many who do not hate the BT are simply bored by it.
The BT fears Southern football, and the midwestern located power ND in the Southern based ACC is a deep fear because the threat is so great.
There are only 2 leagues that have been in the playoffs every year. The SEC and the Southern founded and Southern based ACC. You get ND, with its unique national fan base and national recruiting power, to move from 5 ACC games per year to the full slate, meaning ND is part of the race for a berth in the ACC Championship, and ACC football TV numbers will go up even more, as will the ability of ACC teams to recruit nationally, but especially in the midwest: where ND is located near Chicago, and where the BT MUST totally dominate recruiting and TV audience.
