"This chart comes from a paper presented by Theodore Goudge, an associate professor in the department of geography at Northwest Missouri State University, at the 2012 Annual Meeting of the Association of American Geographers. It pretty clearly shows what Goudge referred to as the “pigskin cult” of the south, to which the Big Ten footprint does not extend. With the glaring exception of Ohio, there is no dark red in Big Ten country; the map only gets paler and paler the further Northeast it extends, where there are more televisions but fewer prospects."
