The rankings are really, really close though when you look at the raw point totals. It wouldn't take much for them to jump those 4 spots.
I looked at the old BCS computers. One of them has a site that averages out basically every college football computer ranking known to man (some I'm sure that are more geared towards resume, and some that are geared towards who is projected to be the best going forward). Here's the top 10 of that composite ranking
1. Oregon, 2. Ohio State, 3. Penn State, 4. Miami, 5. Texas, 6. Georgia, 7. Notre Dame, 8. Alabama. 9. Indiana, 10. BYU
