Tszyu and Golovkin are both a poor man's Arbachakov. Word. The original Gato Gonzalez was a poor man's Napoles though maybe too talented to be labelled as such. Same for Conteh and DeJesus to an even greater degree. Similar styles. Eubank also had similar upper body and head movement to Naps, old school defensive positioning etc but not as good. Tae-Shik Kim was a flyweight poor man's Duran. Anselmo Moreno was a very poor man's Whitaker/Zapata. Yamanaka was a poor man's Ebihara/Gushiken. Barrera a poor man's JCC.
Juan Baby Bull Diaz was a Poor Man's JCC Great Stamina, strictly an inside fighter like JCC. Unlike JCC, no power & often followed as opposed to cutting the ring off like JCC did. But he sure was exciting to watch!
Actually, I will correct this and say that Roger Mayweather was a poor man's Thomas Hearns. Donald Curry was a poor man's Sugar Ray Robinson. No knock against Curry, he was a great fighter in his own right. Sam Peter as a poor man's Ike Ibeabuchi was a good call. Greg Page a poor man's Muhummad Ali. Jorge Luiz Gonzales was a poor man's Teo Stevenson.
Chan Hee Park is 'Version 1.0' to Jung Koo Chang's '2.0'. Ivan Calderón was a discount Miguel Canto. Naseem Hamed was a poor version of Tony Canzoneri. Mikey Garcia is a poor man's Barney Ross.
Rocky Marciano was greater than Joe Louis because Rocky beat him when Louis was 36. That the thrust of your argument?
the Louis of 1951 looking for his last paycheck?? why would anyone seriously take this as a valid comparison?
