For good or bad, depending on one' perspective, the pace of things has accelerated including changes in college sports. And things will really accelerate as the pre baby boomers die out.
The points you made in the post I originally responded to have merit. But the dynamics of the current world makes me feel the counter arguments to your position have more merit. Certainly there is an inertia to behavioral change. And the more complex the behavior, such as institutional behavior, the greater the inertia. So what makes me take issue with your post. The things that tend to overcome inertia: the desire for power/money/image. When the value increases for any of these things the rate of change increases.
No one is arguing whether ND has cache. They do. The argument is whether that cache is worth the power/money they are currently getting. This vote by the SEC coaches, imo, was more than just an empty statement. It was the first salvo to challenge the ND paradigm. There are a lot of interests that want to see ND brought down several pegs. And the consensus is shifting away from the belief that ND is a football powerhouse. There are a lot of people in this forum who strongly feel that if ND were in a conference they would struggle and become mediocre if their schedule was more regimented than tailored. IMO, the SEC coaches also feel that way. And imo they have judged ND football correctly. The boost the ACC would get with the initial agreement by ND to fully join their conference could be disastrous to the conference if ND does not perform. The SEC coaches are predicting that would happen.
University leaders had tasted blood when they asserted themselves in demanding a greater share of media money. Egos are getting involved and there will be more and more decision makers who want to assert their control over things. ND, even with its cache, would be the perfect entity for the power three conferences (The ACC and the Texas conference are more reactionary imo) to send a message to the NCAA and the media entities they are associated with, that the universities in these three conferences are the ones controlling things. ND is on thin ice because the network they are affiliated with is not sending monies to any of these conferences. Certainly ND will still have NBC's contract but the loss of the generous bowl agreement they currently have could accelerate ND's football decline and marginalize NBC in the process. The SEC coaches are betting ND will become mediocre either way and that reduces the pie significantly. It would be the same reduction as the choice to squeeze out all the non power five conferences.
Once a wild animal tastes blood, the desire for more blood is increased. And there is a little bit of wild beast in most of us, even those who mask it well.
