I do find it interesting in this day of NIL that SEC "ascendancy" may be attenuated. (I never thought it was all that terrific back when, very solid no doubt.)
The "SEC Helmet" is still a thing, I think. Folks put a lot of emphasis on which team wins the NC of course, and which league. I look broader than that, I think it pretty clear the B1G and SEC are ahead of the others, and probably close to each other.
