 The university's longest active football rivalry is with Navy (dating back to 1891).This rivalry stems from Navy and Rutgers being two of the only three programs (the third is Army) to come out of the original, informal "Ivy League" that are still members of the top tier of NCAA college football (currently Division I FBS).Rutgers was a part of a round-robin conference known as the Middle Three Conference in football from 1929 through 1976, which included Lafayette and Lehigh.
