Last week, the Southeastern Conference was proclaimed the best in the land for 2008. This week it's the Big 12. Total nonsense, of course, because more than half of the teams have been getting fat on cupcake opponents.

A true test is to compare how the Bowl Championship Series conferences have fared against each other for the past 10 seasons. For the answer, we once again turned to Ed Gunther of National Championship Issue.

Ed recently compared conference vs. conference records, including bowl games, from 1998-2007. By percentage, the Pacific 10 won 54.5% of its games against BCS opponents. Here is the breakdown:

Pacific 10: 54.5%
Southeastern: 50.8%
Big Ten: 50.5%
Atlantic Coast: 50%
Big 12: 48.8%
Big East: 45.9%

We took Ed's data and charted how the BCS conferences fared against each other. Two surprising numbers. First, the Big East was only 10-20 against the Big Ten. Second, the SEC was only 8-17 against the Big East. Here's the data. Have at it. As always, click a chart for an expanded view.
