In all honesty, I enjoy watching PAC football. It's very different from the game played down here, so it's always good to see something different. Watching Oregon, AZ State, Wazzou, Cal, UCLA, etc. can be entertaining.
My opinion is that the PAC is the second best conference out there. Are they the SEC? No. But they are a deep conference. There are no really easy outs in that conference. Most teams can score enough to beat you on a given night.
Here's where I think the difference is. Physicality. The SEC just beats you up week in and week out. Even when you play a bottom half of the conference team(Arkansas, Kentucky, TN, FL this year), you get beat up physically by in some cases big OL(Arkansas) and in others by physical defenses(FL). Ole Miss is in the middle of a 5 game stretch that includes Bama, TAMU, TN, LSU, and Auburn). The physical toll a stretch like that takes on you is just brutal.
Again, I enjoy watching Oregon play. Mariota is a freak athlete, and just a hell of a QB. But I think if Oregon were in the SEC, the physicality of an 8 game SEC schedule would be tough on them. Not that they couldn't get through it, but there smallish OL would find blocking SEC defensive lines difficult.
