I just saw this, and it hadn’t crossed my mind.
The top 4 seeds go to the Top 4 ranked conference champions.
If and when BYU takes a loss, there is a decent chance that Boise State is ranked ahead of the entire Big 12 conference.
If they finish out winning the rest, and the Big 12 champion is ranked lower, then the Big 12 champion is going to end up as that 12 seed, and Boise State would be the 4.
