The Army-Navy football game has a little something for everyone. Purists see it as a true contest among "student athletes." Old-schoolers love the triple-option running game. The patriots among us savor the pageantry and pre-game march-on. And, of course, CBS television likes filling an empty Saturday date after the advertiser-friendly SEC games are over.But whatever the viewpoint, the game is inarguably a chapter in a storied American sports rivalry. The matchup on Saturday in the Washington Redskins' home stadium will be the 112th between the two service academies since they began playing each other 121 years ago. Hmm. What happened in the other 10 years?Excessive game violence and fan rowdiness caused a five-year hiatus, 1894-1898. Death of a player, 1909. The War to End All Wars, 1917-1918. Interservice bickering over player eligibility rules, 1928-1929. You know, normal football stuff.
