Ya know, I just find it difficult to support any CFP. And the Bigger it gets, the worse it is.
Example: It is a distinct possibility that 3 SEC Teams and 3 Big 10 Teams could make the CFP in the same year. That gives you 4 teams that didn't win their conference and two teams that couldn't even win their own division, vying for a, so called National Championship. Ain't ever gonna happen??? Hmm, and when it does., then what? Certainly, Michigan/Bama was a fantastic game. And so was Army/Navy.
You mentioned 'exciting' so, just consider for a moment, what the quest for this Holy Grail CHAMPEENSHIP does to the rest of the season. Akron, Old Dominion, Vanderbilt and Wofford and we are still virtually guaranteed of a losing season and so, wouldn't it be a more fair indicator (more exciting and wiser, as well) if in the chase for this beloved Crown, ALL P5 teams could only schedule other P5 Teams?
No need to beat me up. I fully realize that I'm the only one who sees the CFP as pure folly.
