I’m still unsure how to rate old time fighter relative to modern fighters, but in this one it feels like common sense. Beterbiev walks in at what 190+ and has a very deep amateur background. Marciano started boxing at 24 and had very few fights as an amateur. Common sense says Beterbiev should win this I think.
Factoring in the rehydration of the big LHWs these days, like the 6'3" Smith for example. Were the HWs Marciano was fighting actually bigger than the guys Artur has fought?
What exactly do you mean by this... that Beterbiev is a modern sissy, who doesn't compare to a real fighter like Marciano?
