All-Tonawanda were the 1917 champions of the New York Pro Football League, defeating Rochester Jeffersons. The New York Pro Football League (NYPFL) was a professional American football league, active in the 1910s, and based in upstate New York, primarily Western New York. Between 1920 and 1921, the league's best teams were absorbed into the National Football League, though none survive in that league today. It was one of the biggest challengers to the Ohio League in professional football in the 1910s.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
