The link above is a mapping site/blog that explains college football through maps. This site includes maps of the geographical areas of teams, the history of college football, playoff expansion, and other information. My favorite part about this site is how it maps the USA based on favorite teams within each state/area which I thought was a cool visual. People are also able to comment.
