As a reference, I’m posting the closest to final rankings I have for the early years. When the GCR started, I only ranked the FBS teams and only through rivalry week (usually), because I didn’t have the ability to have “repeat” games in which two teams played more than once. Because of that, the Army/Navy game is not included nor the bowl games. Once I couldn’t continue, I stopped. Here are all the rankings from top to bottom in 2015
