You still avoided the question.
What logjam is there at B and C?
There is almost NO ONE playing C or B. Conference has nothing to do with that. If you had C and B state programs with B teams having no place to go I would totally agree with some of what you are saying.
If you have most states with no B teams and most states with no C program, why does it matter that a few teams play A, AA, and Major?
