What is the best Conference in College Football?

I say the big 12. I know you can say well they don't have that good of defenses but their offenses are unstoppable I mean Colt McCoy, Sam Bradford, Jordan Shipley, Todd Reesing, Dezmon Briscoe, Dez Bryant, Kendall Hunter, and Zac Robinson thats just unbelievable. Plus Nebraska and Texas have good defenses. Mack Brown, Bob Stoops, Mark Mangino, Mike Gundy, and Mike Leach are all great coaches and all in the Big-12. I'm not a fan of any Big-12 team.
