Oklahoma and Arizona St got in soley based on their wins. Losses don't even matter anymore, just go at least 18-14 and beat 2 or 3 top tier teams and you are in??
Weird though, Oklahoma St had better wins than Oklahoma and beat them 2 out of 3.....so I give up on trying to understand the selection committee, I don't think they have a clue either.
It really isn't as hazy as you are making it out to be. The committee has been very consistent rewarding teams with a strong OOC record/strength of schedule and that was the case again this year. IMO the team with the biggest gripe is St Mary's. They absolutely should have been in the field over ASU and Syracuse but the metrics didn't work in their favor. I do think that the committee needs to have a what "have you done lately" approach as well because there are few arguments on why OU was in over OSU other than RPI.
