When you look at the past 15 national champions in the BCS era...one stat that sticks out is scoring defense. With the exception of a few teams, the final champs have been stingy with points allowed and yards given up.
1998 Tennessee (Defense held 9 of 13 opponents to 18 points or less)
1999 Florida State (Led ACC in total defense with 302.6 ypg)
2000 Oklahoma (No. 8 nationally in total defense at 278.9 ypg)
2001 Miami (No. 1 in scoring defense at 9.8 ppg)
2002 Ohio State (No. 2 in scoring defense 13.1 ppg)
2003 LSU (No. 1 in total defense 252.1 ypg)
2004 USC (No. 3 in scoring defense 13.0 ppg)
2005 Texas (Averaged 50 points per game)
2006 Florida (Held Ohio State to 82 total yards in title game)
2007 LSU (Only two loss national champions)
2008 Florida (No. 2 in scoring defense 12.9 ppg)
2009 Alabama (No. 2 in total defense 244.1 ypg)
2010 Auburn (Cam Newton 4,327 yards of offense)
2011 Alabama (No. 1 scoring defense 8.2 ppg)
2012 Alabama (No. 1 scoring defense 10.93 ppg)
What's the old saying? DEFENSE wins championships!
