This is not necessarily true. Let's be specific for a moment. The teams in the SEC WEST like LSU and Alabama do go out of conference periodically and get some quality games. LSU has gone to Oregon, Washington, Dallas and Houston for openers. Alabama has had a home and home with Penn State, opened the season win kickoff classics several times... Arkansas regularly plays teams from the BigXii, Auburn has had home-and-home with Clemson and has opened in Atlanta a couple times. The two teams in the SEC West that haven't schedule out of conference are Ole Miss and Mississippi State.
The SEC East is a completely different story for one BIG reason: The Eastern teams (for the most part) have annual rivalry games with the ACC. Florida/Florida State, Georgia/Georgia Tech, South Carolina/Clemson, Kentucky/Louisville are on the schedule every year. The teams in the SEC West don't have these annual out-of-conference rivalries. Additionally, Georgia has added Arizona State, Boise State and Clemson to their already packed schedule.
So no, the SEC's scheduling is just fine, thank you very much.
By the same token, I do NOT agree with Vader's criticism of Ohio State's schedule. Buckeyes have scheduled NIU (a bowl team last year) and opened the season on the road in Blacksburg. You cannot fault Ohio State for their confernece schedule. The B1G being down is just to thier benefit. Nothing you can do about that. Is Urban Meyer supposed to recruit for Penn State and Indiana too? The B1G teams need to get their act together. Northwestern being the 3rd best team in that conference says all you need to say. Can you imagine Vanderbilt being the best team in the SEC... EVER?
I will give Vandy credit in that they have the best looking cheerleaders in the SEC. Like ever. They are hot!
