They are getting way too much credit for being down 3 scores and Ohio State getting too cute with their play calling...
OSU could've just ended that game by kicking a FG but Day had a complete brain jam. Just an absolute terrible decision to go for it on 4th given the time and situation. Unless his kicker is hurt that was about the easiest decision ever - kick a chip shot to go up two scores.
Indiana is certainly a pretty good team, but their resume is beating teams that have a combined 4 wins, maybe, and a backdoor cover. And a highly questionable call to get the win over terrible PSU.
I don't think Northwestern is better than ISU, but if you are 5-0 and have played a reasonable power conference schedule I think you've earned a top 12 ranking. I am much better with NW being where they are than Indiana.
I don't think we really have much to complain about pollsters. Since 2017 ISU has typically been one of, if not the highest ranked team with X losses.
