I think pretty much anybody in the top 6-8 is the ‘best talent’ and so that point is kind of moot. I speak only for myself on this, but I am more interested in new match-ups and I don’t care if that is Baylor, Utah or Oklahoma. I’ll see LSU and Georgia play this week, I don’t want to see that again and if that happens I doubt I would bother to watch.
And this isn’t just an SEC thing, I feel the same way about the NCAA b-ball tournament (with the provision of at least if two conference mates played in the championship game at least they earned it through the tournament). I think the playoff should establish who the best team is in the nation at the end of the season - and if Georgia beats LSU, LSU isn’t the best team in the nation. To me it makes sense to have the diversity of conferences to see if the PAC-12 is really as inferior to the other conference as is claimed.
And again, I know this isn’t how it currently works, but for me that would be of far more interest whether Utah was in the convo or not. For example, if Utah falls to Oregon, I really don’t want to see Georgia and LSU, I’d rather have Oklahoma. Same for other conferences. If for some reason the top 5 teams were in order Oklahoma, Texas, OSU, Clemson and LSU, I’d say it should be the winner of OK and Texas, OSU, Clemson, and LSU.
In short, I don’t care about rematches and never will, and I suspect I’m not alone in that. Go to a 16 team playoff like you’ve proposed then yeah, they’ve earned the right to be there.
