Take a look at how often the SEC got to play the pac-10 on its home turf throughout the last 100 years--probably more than 80% of the time.
The reason the head to head records are evening out if not leaning toward the pac10 in the past twenty five years, is that now the teams are playing home n home schedules...
If that overtime LSU game had been at Oregon State would the Tigers have won?
The Pac10 pro style offenses are hard to stop...even for SEC defenses.
all of that said, the SEC still gets my vote as best conference, but the Pac10 is VERY underrated by the national sports writers, and pollsters.
