"...The Rochester Jeffersons had only three official uniforms. During the period of around 1905 through 1913, some of the players had a "J" on the jersey. Around 1914 till 1919, the team wore the "Jeffs" across the jersey. Those were the semi pro years. In 1920 to 1925, the NFL years, the team wore the plain red jersey you described. So no, the Jeffs script jersey was never worn in the NFL, only the red one with white stripes."
