To MDT point: 13 out of 32 is much different than 13/50 or 13/75. Make your cut wherever you want, there are 130+ D1 teams, but IMO only about 50 deserve to be there. It should have been capped a long time ago, with the ability to demote, and criteria to promote.
Now look up the total number of teams that PLAYED for the SB, and lost. Sure, you’ll have your NE that lost several and won several but you’ll also have the Bears and SF and all the other teams. I’m betting you’ll have at least 20-25 teams out of 32 and reached the SB. Hell, 30 years ago I think the Cowboys are in the W column. And then if you look at all the teams that reached their conference championship or at least had a good season and were in contention I think you’ll capture everyone except the Browns. Texans may have even reached the CCG,I really don’t follow them very much.
Now look at CFB, a team like Ole Miss has never played in the SEC CCG in 30+ years, hasn’t won a conference title since the 1960’s. Same for Kentucky. The system never works for these teams, even in the pre-BCS era, the 4 team playoff, the BCS era. Arkansas has been lucky to reach the CCG 3 times, but hasn’t won the conference since the SWC in maybe 1990.
