Yup. As I've written before, amateurism has an appeal. NIL, opt outs, portal, etc make CFB look like professionals. When CFB players act like professionals and CFB conducts itself like a minor league, the appeal of amateurism fades. No one cares about the minor leagues in any sport. This is also why interest in the olympics has waned. After great interest in the novelty of the 1992 Dream team, no one cares about olympic basketball. People can watch pro basketball, tennis, hockey, golf, etc every day. There is little appeal in watching the same people in the olympics.
Personally, I didn't watch a single bowl game, including the outback bowl. With all the opt outs, I realized that the team playing would not be the team I invested in all season. There was little appeal to me to watch a "blue-white" game against Arkansas. People defend the opt outs by saying that the kids "owe fans nothing." Maybe.
I'd suggest that it's the fan investment (emotional, monetary, time) that provides every resource and opportunity that CFB players enjoy. When CFB players walk away and don't honor that investment, it logically creates negative feelings to those who have invested. We can debate whether the players "owe" fans anything, but there is no doubt that the current state of CFB (opt outs, NIL, portal) will drive less fan investment and therefore fewer dollars/resources and a shrinking of CFB. We can debate whether it's good, bad, or indifferent, but it's a reality.
IMHO, we will see a major shakeup of CFB as TV contracts adjust to this diminished interest reality.
Bowls are dead, or will return to what they were 4 decades ago.
Power teams who face less geographical pro competition and that have long operated as "semi-pro" will form a ~12-20 team P1. The rest (including PSU) will reorganize into a 2nd tier CFB system. The existing conferences may remain, they may not. Less TV money means more red ink. A percentage of the 130 FBS teams will drop to FCS or fold.
The US is about the only country with Major college sports. In the long run, we could see current college "revenue sports" follow the rest of the world with development pro ranks and college sports being played by students, without pro aspirations, who play as an extra-curricular.
As Nietzsche might have said, "College Football is dead, and we killed it."
