A pair of Jacks from the early 1900's, James Hagen vs. Janos Ruthaly...to use their original names. They fought about the same time and were apparently both (mostly) lightheavyweights, therefore had some of the same opponents, in addition to also fighting heavyweights (as many lightheavys did then and since).
But they never got around to fighting each other. How do you see such a fight going and who, if either (there were many draws/no-decisions in that era), would have won?
