To me it’s Ohio State, Texas, and Georgia as top dogs in the NIL era moving forward, with Michigan, Florida, USC, Oregon, and Clemson (if they don’t let Dabo run them into the ground) all capable of moving into that top group long term. If Harbaugh stays then I think you’d have to include Michigan in that top tier now.
Then I think Bama is in a tier of its own due to prestige, current state of program infrastructure, etc. It’s hard to predict what will happen to them when all we can say for sure right now is “multiple teams have caught up to them and one for sure has passed them” and they just lost the best college coach of all time.
Then you have ND, LSU, Aggy, Penn State, Washington, Auburn. I may be missing someone. But all of those programs feel like they have certain institutional issues that prevents them from competing at a sustained top 3-5 level year over year moving forward.
