Easy BamaFan615, take a chill pill and unwad your panties. Nobody is claiming that Kansas State is a "powerhouse." You can take different numbers and statistics and twist them around to say whatever you want, but in the end it's pretty simple.
The BCS ranks the Big 12 as the toughest conference, ahead of the SEC. Oklahoma State went 11-1 and won the Big 12. Alabama, (who also went 11-1), failed to even win their own division, much less the SEC. Add to the fact that they've already lost AT HOME to the other team playing in the championship game, and it quickly becomes clear that Oklahoma State should be playing in the national championship game. In addition to all of that, the before-mentioned "other team" in the championship game is also in the SEC, which means a conference that isn't even ranked number 1 has both teams in the national championship.
