I know it's early in the season but I always enjoy going to http://masseyratings.com/cb/compare.htm to compare the dozen or so main ranking systems out there to see where we stand across the board. Sometimes it takes a while for them to update, but it's very convenient and has individual links to every ranking system they use. My personal favorite is the Sagarin ranking from USAToday which relies heavily on Win-Loss and schedule strength.
As a sports statistics junky, I enjoy this stuff a lot. ;D
