If there as an SEC/Pac 10 show down, matching up the #1 teams from each conference, #2 teams, and so on, there is no doubt in my mind the SEC would win at least 7 of the 10 games. The top teams in the conference are evenly matched, but when you get to the mid-lower levels of each conference, this is when the SEC seperates iteself from the Pac 10. The middle teams of the SEC are Auburn, Tennessee, and two out of Alabama/South Carolina/Arkansas. Pit these "average" SEC teams against average Pac 10 teams, and it would get ugly. Arkansas vs. Oregon State? Arkansas blows the hell out of them. Have you seen McFadden and Felix Jones play together? Damn, they had that season last year without a passing game to speak of!! Tennessee vs. Oregon? As much as I hate Tennessee, they would win walking away. Remember what they had last year that Cal didn't? Speed all over the freakin' place, the SEC thrives on it more than any other conference. Not to mention, most SEC teams are very physical as well.
The #9 and #10 teams in the SEC are Kentucky and Vanderbilt. They would destroy whoever the bottom two teams in the Pac 10 are (Stanford and Washington?). The strength from the SEC is from top to bottom, not just the top like many other conferences.
