Last Saturday neither Oklahoma nor Oklahoma State were playing football. Kansas and Kansas State also had the weekend off. I had the option of watching some football involving teams that I’m not partial to or doing chores around the house. While I was mulling my options, I did turn on the big TV in the den and saw a portion of the Indiana- Michigan State game. While watching, I learned that the winner of that rivalry gets to claim possession of a traveling trophy known as the Old Brass Spittoon. Hearing that information, my mind started wandering.....what are some of the other great college football rivalries?
