I bring up transitive property and Sagarin in my debate with you because I know you believe in them. I think transitive property can be a decent indicator, but certainly not the be all end all. It's kind of like Sagarin, 70% legit, 30% pretend. Teams match up differently with one another. Home teams (Ohio State) , trap games (Northern Illinois), injuries, rivalry games (Michigan) , bye weeks.........all can play a factor. But at the end of the day, it was hard for the committee to ignore how Indiana won their games impressively. They earned their way in, whereas Alabama did not.
