The 1918 NCAA football season had no clear-cut champion, with the Official NCAA Division I Football Records Book listing Michigan and Pittsburgh as national champions.^[2]
The Spanish flu pandemic of 1918 saw the implementation of quarantines that eliminated much of that year's college football season.
Perhaps the highest profile game was a highly publicized War Charities benefit staged at Forbes Field in Pittsburgh in front of many of the nation's top sports writers, including Walter Camp. The game pitted John Heisman's undefeated, unscored upon, and defending national champion Georgia Tech Yellow Jackets against "Pop" Warner's Pittsburgh Panthers who were sitting on a 30 game win streak. Pitt defeated Georgia Tech 32-0. Taken from http://en.wikipedia.org/wiki/1918_college_football_season.
