Based on resume, Oregon should be a #1 seed. They have wins over solid teams and they were the PAC-12 regular season and tournament champs. The "bracketology" that I saw last night had Oregon as one of 6 teams that should be in strong consideration for a 1 seed.
Also, I hope USC was paying attention. That is how you impose your will on a team that you have the advantages in speed and athleticism against.
