Participating in the loose New York Pro Football League, the Jeffersons resumed full play after playing only two games in 1918. The Jeffersons won the Rochester circuit with a 7-1-1 record, mostly against lower-level upstate teams, only to lose the New York Pro Championship to their regional rivals, the Buffalo Prospects.
