Nice idea.
IF you want a soul crushing long slog to one and only champion and everybody else is a POS.
We have that. It plays every Sunday.
Games matter. In and of themselves, for deep historical reasons. Much of which is not understandable to people outside the traditional college football footprint.
It is WAY more important than determining some national champion.
I'm having trouble researching when the National Champion in college football didn't matter. Google keeps giving me a result of "You are wasting your time". Comparing the alleged top five teams, then comparing them despite them never playing each other was a fools errand, always was. College Football rankings screams "inadequate sample size".
'96 come to mind with OSU. Okay... OSU beats ASU... FU beats FSU. The national champion is... FU! Like literally. Ohio State loses to Michigan in one of the "traditional" games you mention (but that tradition is completely ignored in the ranking process) and they lose the national title because of it... and FU split with FSU... and for some reason, because FU's victory was a number of weeks after they lost to FSU, FU gets the title?!
Late November, FU is #1 and FSU is #2. Whoops, FSU won, FSU is #1 in the country. January, whoops FU beat FSU, which means FU is #1 again. What about OSU? They just beat #2 ASU. Meh! They lost to Michigan in November. ARGHG!!!! The funny thing is, Florida was a near unanimous selection, so the controversy is just in my head, but it is real. Additionally, Arizona State beat one ranked opponent that year. So technically, OSU was never going to be #1 no matter who won in the FSU and FU game.
BTW, 6th in the SEC wins every other league. The haters have now come up with this idea that the SEC is some how "lopsided". It is easier than accepting the reality that it just is that much better, top to bottom, than every other league.
Well haters got to hate. And the SEC are a bunch of bums because they keep winning all the time. Darn Bums!
