The best college football rivalries can change over time. Go back 25 or 30 years and Miami-Florida State probably would have been near the top of most lists. Some rivalries have largely gone away, including Nebraska-Oklahoma and Texas-Texas A&M. The Associated Press asked a panel of sports writers and broadcasters to rank the best rivalries in college football. Four longstanding series separated themselves from the rest, topped by Alabama-Auburn, Michigan-Ohio State and Army-Navy.
