Neither Iowa or Bama are statistically significantly different than ISU at the 95% significance level. Though Bama is statistically significantly better at 90% significance. I'm not disagreeing with your point, but people need more than just W-L data to draw any conclusions.
I didn't really have a point. I just like to pull data to try and put things into context since I know that I, like most, can get caught up with recency bias.
I honestly was surprised that Iowa wasn't better at close games than they are.
I pulled Alabama numbers because they're the gold standard of CFB.
My theory is that close games are a lot like turnovers in that it's a bit of luck, a bit of skill, a bit of discipline/leadership, confidence/belief, and who knows.
