OK, so we just don’t agree on how important winning the conference championship is. That’s a point reasonable people can disagree on.
I hate Alabama, but I’m OK with their being in the tournament. I’d also be OK with a college hockey team that comes in second in their conference during the regular season, getting bounced in the first round of their conference championship, making the tournament based on their PWR, and winning the national tournament. Presumably, you wouldn't be.
I am curious as to how you arrive at the conclusion that Alabama had a weaker schedule than Wisconsin. I don’t know what algorithm the NCAA uses, but using
this one (which has the advantage of being able to get rankings on a specific date) here are the rankings for Wisconsin and Alabama:
Completion of regular season: Alabama 7, Wisconsin 45
Following conference championships: Alabama 10, Wisconsin 20
Following Orange and Sugar Bowls: Alabama 6, Wisconsin 14
End of Season: Alabama 2, Wisconsin 14
