I agree with what you said, but that was PREVIOUS years ...Not really, 1-loss teams for other conferences have made it in (Oregon, Ohio St (twice), Clempson, Michigan St, Washington, and Oklahoma (four times), in addition to Georgia and Alabama (3 times).
In each case that a 1-loss team got in, there was no other undefeated P5 team available. There has never been a 2-loss team to get in. So where is the SEC advantage?
Even in the year where the SEC got 2 teams in, the Big Ten and Pac 12 Champions had 2 losses apiece. If Ohio St had lost to Wisconsin, then Alabama would have been left out in favor of Wisconsin, so blame your team for Alabama getting in (personally I think UCF should have been chosen that year instead of Alabama).
With them only playing 8-10 games this year, I think it will be harder to get in with a loss, unless somehow everyone has one.
Depends on what the committee decides to emphasize this year ....
It should end up all 4 conference winners (provided records are comparable) ... but you never know.
