It already does and has been that way for a long time. I suppose you could say that the 10 or so programs who have all been buying players at an elite spending level have the differences settled by coaching and other factors, but I'd argue that the SEC and Bama have long been spending more on players under the table than anyone not named Texas. Texas gets nothing for all the money they put in and maybe throw you off the scent of what's been going on?
In the 10 years that the CFP has been held, there have been 15 unique teams participate. Here's the complete list:
BIG (9): Michigan (3), Michigan St (1), Ohio St (5)
SEC (12): Alabama (8), Georgia (3), LSU (1)
Big12 (7): Oklahoma (4), TCU (1), Texas (1), Cincy (1)
ACC (7): Clemson (6), Florida St (1)
Pac12 (3): Oregon (1), Washington (2)
Indep (2): Notre Dame (2)
Just look at the schools who have participated 3 or more times in a 10 year window. Heard anything about how those schools recruit?
