Week 1 represents what will likely be the biggest shake-up of the season.  Part of this was because of the slate of big games (sorry Clemson), and part of this is because the biggest swing in the computer ratings typically comes right after the first game (hello Michigan, Iowa, Utah, and UCLA).  Barring a 2007-like glut of upsets, you should expect things to stabilize from here on out.

The conference races also got weirder.  Buffalo (?) is now the team most likely to win its division.  Iowa takes charge of the Big Ten West.  Oregon looks like it will win the Pac 12 North by default.  And Virginia Tech is currently sitting atop the ever-mercurial Coastal.

Week 2 is still the "weakest" Saturday of the year per my Playoff metric, but this all looks fine to me.  El Assico will be a fun coinflip.  Ohio State gets to see if it can make another mediocre offense look occasionally great.  And NC State can (and probably will) put a hurting on Mike Leach.
