Insecurity? Nope. Logic.
Ohio State played the ---66th--- ranked schedule. I mean really, it was full of cupcakes and mediocre teams. their best win before the Michigan State game was against Wisconsin, who is struggling to stay ranked. Not to mention the fact that they barely survived a Michigan team that almost lost to Akron and Uconn.
Then you look at Auburn who beat 4 ranked teams in their schedule including #1 and #5 back to back and whose only loss was to a team OSU probably would lose to as well (LSU)....not very hard to see why SEC fans were sour about a team like OSU possibly getting in over a team that actually had to earn their way there through a tough schedule. It would have been a farce had OSU gotten in over Auburn.
Now by the same merit, FSU played a very weak schedule ranked #61. However they never even struggled in their schedule, so there was really no question about them.
Thank goodness the playoffs are coming next year. No more backing into the championship game because of a weak schedule.
Now go Auburn. Not only do I despise FSU, but the fact that they have a QB like Winston with a "did he, didn't he" story forever hanging over him makes me hate them even more.
