According to the leading philosophy of the OTNB community, the longer ago a fighter reigned the greater their boxing acumen was.

I already heard how the great Muhammad Ali could dance his way to a victory against Wladimir Klitschko.

I've already been schooled how Joe Louis would be a challenge for Lennox Lewis.

Recently I have found myself humbled that Jack Dempsey is a deadlock for Mike Tyson,

And Jack Johnson is the equivalent of Vitali Klitschko.

Therefore the next logical step in this saga would probably be John L Sullivan?

Surely he must have been the greatest boxer who ever lived? I mean given how far back that was, there mustn't be anybody who could hold a candle to this drunken booze bag today or in recent times?

I expect Sullivan to be able to massacre Riddick Bowe within a round or 2..

Agreed
