The impressive thing to me is that the five best teams, if we're going by current level - basically, who would Vegas favor, are probably Georgia, Michigan, Ohio State, Washington, Texas. Bama would be sixth at best, but they're leap frogging two better teams to be in. If we go by resume (which is how it should be done), it's gotta be Michigan, Washington, Florida State, then argue about Texas/Georgia/Ohio State. But we didn't get that either.
It's pretty clear that Michigan and Washington were both in. Then they worked backwards. They decided the SEC absolutely had to get a team in... And they couldn't pick Georgia over Bama, so Bama was in. Then they had to decide between FSU and Texas, and Texas won at Tuscaloosa so if you leave them out it's insane. Leaving FSU out is also insane, but you get the injury argument to fall back on. But the bottom line is, they were never going to have zero SEC teams, and they worked backwards from there.
The next time they revise the system it'll be to remove the auto bye and home game for winning your conference, and the top four will always be SEC/B1G.
