The integration of NIL deals will have a much larger effect than the conference transitions for the state of TnF. Now that companies can essentially back athletes, the schools that have a steady flow of NIL deals (think same company conveniently giving deals to multiple athletes on the team year after year) will perform which will aide in recruiting more talent (from HS and internationally) because recruits know the money is likely already there.
Not all, mater-a-fact, I suspect most, schools in the near future won't have this luxury as the NIL model is still in development. The P5 schools (namely SEC and BIG 10) will be more attractive sure. In terms of recruiting talent; the rich will get richer and the poor will get poorer. I think this will lead to several teams consistently being at the top leading to a reduction in the likelyhood of powerhouses (NAU XC, TAnM/UAr track and times) due to saturation in talent at the top.
