Pop quiz, college football fans: Who has the longest active winning streak in what for years was known collectively as Division 1 college football, but now goes by the awkward NCAA argot of Football Bowl Subdivision (née Division 1-A) and Football Championship Subdivision (née Division 1-AA)?

Alabama, Oregon, Notre Dame, and Florida are all valid guesses. But the honor belongs to its oldest and most distinguished institution of higher learning — Harvard. The Crimson (5-0) have won 14 straight games, dating to 2011, heading into Saturday’s showdown with Princeton.
