Pac10 went 5-0 in bowls last year...
..proving it is far more than "Just USC".
I believe the pac10 is like 12-10 vs the SEC since 1998. If you took out the AZ schools who changed the pac8 to the pac10 and are 0-3 vs LSU and 0-2 vs UGA, it would be even worse.
Now I grant you none of the wins are over the top 2 dogs of the SEC, LSU and UF, but still you have to give the pac10 credit. In 2009, there were 3 games between the 2 conferences, SEC won 2 of them, had home field in 2 of them, and each game was decided by single digits.
There is not this huge gap between the 2 conferences that some like to say there is.
