SB Nation BlogPoll College Football Top 25 Rankings "

Explanations after the jump.

• The first tier -- the top three.  Oklahoma moved backed in after their pasting of Texas at the Red River Shootout.
• The second tier -- 4-7.  While not quite as strong as 'Bama, LSU, and OU, Wisconsin, Stanford, OSU and Stanford have generally looked impressive in most or all of their games.
• The third tier -- 8-13.  Undefeated teams with lesser resumes or teams that have looked shaky in some games, plus Oregon.
• The fourth tier -- 14-19.  Teams with at least one good win to go along with at least one loss.
• The fifth tier -- 20-25.  I don't really know what to do with these teams.  Your guess is as good, if not better than mine.
