Ranking the Greats: your assistance please

This endeavor is since 1920. I will say that Gans would have ranked very high. Probably well inside the top 10, although his era poses a range of problems that force me to exclude them from P4P rankings of what really is a different era, the modern era.

Fitzsimmons would rank high if he was ranked relative to his own time, but I personally consider most of the fighters from the era before 1920 to be "pioneers". Their style was different because the sport was basically a different sport when you factor in the number of rounds, the lack of rules, the NDs, and the higher rate of shenanigans. Even Sam Langford, who was as great as it gets, has a record with more than a few dives and carries.
