Every week, Jerry Palm updates his bowl projections based on that weekend's games. I believe at the beginning of the season he had OSU winning it all, and even after the OU loss, I don't think he ever took OSU out of the top 4.

His week 9 projections are the same as week 8, except he swapped Clemson and PSU spots.
JP's week 9 projections:
1/1/18 5:00pm - Rose Bowl - #2 Ohio State vs. #3 Clemson
1/1/18 9:00pm - Sugar Bowl - #1 Alabama vs. #4 Penn State
Other games of note:
1/1/18 - Peach Bowl - Oklahoma vs. UCF
12/30/17 - Fiesta Bowl - Wisconsin vs. USC
12/30/17 - Orange Bowl - Miami vs. Georgia (safe travels Miami)
12/29/17 - Cotton Bowl - Oklahoma State vs. Notre Dame
Obviously lots of football to play out, but interesting to follow along.
