I know it won't happen because of $$, but it would seem the answer to all the conference shuffling and CFB playoffs would be to align like the NFL. One big "conference" with regional divisions. Win your region, move to the playoffs.
But with so many CFB teams, you'd need to have a "major league" and "minor league" conference (or maybe 2 minor leagues?). Then (like European soccer) the worst team of the major drops down and the championship team of the minors moves up.
No more dumb bowl matchups...it is all playoff football. It would be drastically different, but an improvement overall. But not without a lot of logistical challenges.
