And I did reward Alabama for a win in that scenario. I think they would be around #9 going into the SEC championship game, but the win and the "bonus" they receive for winning their conference championship would push them up to #4. It could even move them as high as #3, IMO, and I was on the line on where to pick that one.
And I pushed SMU and Colorado who were both in the mid-teens going into conference championship weekend up into the top-10. You could argue they move in front of BYU due to their conference titles (and maybe the committee does that to make their seeding more "clean"), but the end result of that wouldn't change BYU's seeding at those 2 teams would be top-4 seeds in the playoffs.
In the end, I'll concede that with a loss in the CCG and finishing 12-1 they could finish as low as #9 in the rankings, but I think a spot in that 8v9 matchup is a very likely situation if that's how they finish. I prefer to think they would get the 8 seed over Indiana (who I think will lose big to Ohio St.) as they would be 12-1 compared to Indiana's 11-1 (with Indiana having a weaker SOS than BYU), but I admit I could be wrong on that thinking.
