Comment: He passes  having played in the NFL (it was called the APFA at the time, but renamed the NFL the next year).  Most of the regional newspapers that would have covered the 1921 NFL season are hidden behind pay walls or not on-line, making it ''very'' difficult to dig out the source materials without spending a lot of money.  This is why the presumption of notability exists for NFL players. A little bit of digging did show that he not only played pro football for the Triangles, he was also an assistant coach in 1919 in the Ohio League, the regional pro league that gave birth to the NFL in 1920
