I am pretty certain I am remembering that correctly.
I have wondered myself what film convinced Machen of this. But there is a point in the Johnson fight in which Jeffries flurries with both hands and for a big fellow he threw a lot of leather quickly.
I think Machen had someone in his corner that worked with Jack Johnson.
