Perhaps Alabama should have slid a bit further. That said, there was absolutely no injustice done to ISU in its fall in/from the rankings. ISU was overhyped in the preseason both by the media and in-house. Alabama's status is very different based on years of domination.
For ISU, It's gonna be really hard to earn our way back into a 15 or higher ranking. One bitten, twice shy. Alabama will probably still make the playoff.
7-2, and we'd be back in the Top 15
