The Big 12 is the best conference in the country by this computer ranking (the SEC West is good, I'll admit, but the SEC East with Vandy, UK, and USC is a joke this year, as well as mediocre Georgia and Missouri, the only decent team is Florida). The ACC is awful outside of Clemson, and even the Pac-12 is a down year. Evidently having a deep, consistent conference where EVERYBODY HAS TO PLAY EACH OTHER and you can't avoid marquee match-ups against your own best is rewarded rather than punished. Baylor-TCU-OSU-Oklahoma over the next few weeks is going to be fascinating. In the Big 10? Iowa isn't even going to play MSU or OSU until the championship game.
"Offensive/defensive balance" is a complete non-reason for a bunch of people that judge the "quality" of a conference based on the year being had by its blue-blood programs. Texas and Oklahoma are down, the Big 12 much suck, not that Baylor and TCU have developed some very dynamic, innovative talents and offensive systems that are fun to watch and run circles around the lack of growth or innovation at OU and the mess of a program that is Texas. Alabama, LSU, and Florida are good in the SEC? The SEC must rock! I would only imagine what they would say about the SEC if Vandy managed to put together a good run sometime--"it must be really down if they're winning."
It's a crock. Always was/still is.
