"These were the non-conference opponents for the last six national champions, not coincidentally all from the SEC:
2011 Alabama - Kent State,
Penn State, North Texas, Georgia Southern (FCS)
2010 Auburn - Arkansas State,
Clemson, Louisiana-Monroe, Tennessee-Chattanooga (FCS)
2009 Alabama -
Virginia Tech, Florida International, North Texas, Tennessee-Chattanooga (FCS)
2008 Florida - Hawaii,
Miami (Fla.), Citadel (FCS),
Florida State2007 LSU -
Virginia Tech, Middle Tennessee State, Tulane, Louisiana Tech
2006 Florida - Southern Mississippi, Central Florida, Western Carolina (FCS),
Florida StateOf this sextet, only the 2007 LSU team did not face an FCS team and only the 2008 Florida team played more than one BCS conference team (boldface).
Now, this isn't an attempt to take a cheap shot at those SEC powerhouses, as they were only doing what maximizes their chances of winning the national championship. They surmised correctly that playing a soft non-conference schedule does not compromise a team's chances of getting into the BCS title game. What kills them is a loss in a non-conference game.
No team has ever won the BCS title after losing a non-conference game. And only the 2000 Florida State team, which lost to Miami, managed to even get to the BCS title game with a non-conference loss."
