It's not about justification, it's about how the rules work:
"The four highest-ranked conference champions will be seeded one through four and will receive a first-round bye. The fifth conference champion will be seeded where it was ranked or at No. 12 if it is outside the top 12 rankings. Non-conference champions ranked in the top four will be seeded beginning at No. 5. Because of this, the seeding, 1 through 12, could look different than the final rankings."
First of all, pay attention to the last line. Second, the rankings are predicting Boise ending as the 4th highest rated conference champion, regardless of whether they think Boise is the 4th best team.
I love the playoff, I'm familiar with it's structure, but my complaint is decision making with 4 P4 champs and 1 G5 champ.
I am hoping that they swap Boise with the Big 12 Conf Champ winner.
I'm not sure ASU can win 2 more games (which includes the Big XII championship). I hope so.
I think Arizona State plays in a tougher conference with better competition than Boise does in the Mountain West.
And right now ASU has a better resume. 3 wins over ranked teams, and if they win the CCG it would make 4 wins over ranked teams. The Big XII also has 5 teams ranked. The MTN West has 2 - Boise State and UNLV. And Boise State has no wins over ranked opponents. Beating UNLV in the CCG would be their first and only.
I would argue ASU 11-2 with a Big XII championship should be above Boise State in the CFP rankings. At the very least, they should be ranked higher than 12 and should get home field advantage instead of Penn State or Notre Dame (no Conf champ games).
But even though I argue this to myself lol, swapping 12 with 4 is actually no different and would have to go through Ohio State or Oregon (whoever finishes 5th).
If they select Boise for 4th, fine. But at least give the Big XII champ some love with a home field game in first round. I believe those are the odd numbers - 11, 9, 7, 5. That should be required lol. Or give Boise State home field at 11 if ASU is 4th. I know I'm arguing with the clouds, but at the end of the day 6-12 are decisions made by people who have to agree or disagree.
