My favorite rivalry game has to be the North Carolina & Duke game in basketball. Tennessee & Florida in football. Last year that field goal that we made was crazy. I felt like we won a championship or something. Atlanta & Carolina also a game that I always watch even though I turned it off early yesterday. For baseball my favorite team is the Cubs so Id have to say the Cubs & Cardinals. Im not sayin that those are the most popular rivalry games, those are the ones I like to watch
