Oregon's (3-0) resume to USC's (3-0) resume, there really is no logic on why Oregon would be 10 spots higher than USC other than eye test (even then I would say Oregon has not looked that good).
And if we were truly going by eye test then BYU would theoretically be fine in comparing against all the Pac 12 teams.
What sucks about the committee is they use different criteria for each evaluation. So for Oregon, they might use "eye test" but for BYU they will focus on Strength of Schedule (even though Oregon hasn't played anybody yet).
