Shockingly, I'm comfortable with the large move up for the Ducks . We were 12th, we beat #3, we should get a big jump - especially this early in the year when most of the initial rankings were based on "feels" and "thoughts" rather than played games.
Clemson shouldn't have moved with that win, especially after the loss to Georgia, and considering that, as you pointed out, Clemson's offense is not good so far this year.
On a side note - Saban and his post Mercer win rant was...odd. I wonder how his mental game is going.
