Basically, this is a non-scientific study, through observation, of the Big Six programs as determined by HeismanPundit and indirectly CollegeFootballResource (basically, we agree with what he says, and thus, are parroting the concept).
Here's the link, and as of now you can also locate it at the menubar to your left, under "Features".
FYI, the Big Six teams are USC, California, Florida, Louisville, Boise State and Utah. 2004 non head-to-head record of these six squads? 55-2.
