I think the difference in talent recruited after you get by the top 3 or 4 is not that much different until you get to the bottom (Vandy)
I suggested 15 years ago, as SEC dominance was becoming very clear, that recruiting would become like a squeezed accordion. . . . and that there would be less and less room between SEC schools, and that all 12/14/16 schools would be ranked pretty high. This came to pass in 2022 . . . the lowest ranked SEC class was 32nd. Vandy’s 2022 class would have ranked like 4th in the ACC.
I hear folks from the West and the mid-west fret that college football has become a regional sport.
In reality, it always was, at least post-segregation.
There have always been some bright spots outside of Texas, Oklahoma and the SE, and there still are, but had there been playoffs dating back to 1970, the SEC would have won the most, and their main competitors would have been other southern schools in Miami, FSU and Clemson.
The rules predating the 90’s that prohibited No. 1 and No. 2 playing sort of concealed the South’s predominance.
With a 12 team playoff, if things stack up
just right, there will be years when three of the final four are SEC teams, and maybe, rarely, all four.
