I didn't like your reasoning before regarding conference-only metrics for bowl consideration.... but that was before the B1G expansion.
If your suggestion is to work... we would need the following:
Two 8-team divisions, with two 4-team pods each for a total of four pods.
Play everyone in your pod plus 1 from each other pod. Pod leaders enter a 4 team playoff for B1G title. Semifinal losers playback other.
Rest of teams enter "consolation bracket" (2nd vs 2nd, etc).
That's 8 confernce games, including a championship game. Final standings determine bowl eligibility. No need for tie breakers with the playoff and consolation brackets. Allows you to schedule 4 major conference teams every year.
that sounds great till someone doesn't like their pod that yr, or their 3 crossover games that yr.
with a sixteen school conference, there literally is no "fair" way to sched conf games for ranking, without some schools having much easier roads than others.
creating a "formula" to access conf standing is "arguably" more fair, (if the formula if fair), but that has it's issues as well.
and doing as we now do with very imbalanced non conf schedules factoring into bowl and playoff eligibility, is just as potentially unfair as pods or a formula.
point being, there is no perfectly "fair" way to do it, and every yr one way of doing it could be more unfair than others, which each way being more or less fair changing from season to season.
therefore for now, i'll leave how we sched in conf aside, and only speak to the non conf games issue.
besides leaving non conf games completely OUT of any and all considerations for bowl and playoff eligibility totally freeing up schools to sched much more fan and tv friendly non conf games, what it also would do is allow coaches to look at more players in the non conf games, without any fear that one bad play or series can totally f up your season.
coaches could give multiple QBs a look in non conf season under real game conditions, which they don't really get to see much, if any, these days in practice.
same with all the other positions.
does Joe Burrow ever go to LSU, if OSU scheds 3 or 4 non conf opponents against other major conf schools and OSU's coach can give multiple QB playing time in 3 or 4 non conf games.
does the Ramsey/Penix dual a couple yrs ago take on a different light if both get their chance in several non conf games against competitive opponents?
and in both situations, coaches don't have to worry that looking at multiple players at multiple positions in non conf play could affect their bowl or playoff chances.
with the transfers becoming wide open, making the right call on your QB is big, especially since under the current set up, coaches are very reluctant to sub QBs once one is picked from no contact practices, because that 1 bad play or series can sabotage your season with the current rules.
