Hello Z! Mayweather Jr is perhaps the greatest fighter fighting today ad is undefeated but he never met a man like Greb who not only is bigger and stronger but perhaps even faster and able to withstand punches while throwing non stop punches from every conceivable angle. This would be a brutal mauling. Think about it if Greb handled Dempsey in sparring sessions and beat light heavyweights and heavyweights including 18 World Champs and 11 Hall of Famers, he wouldn't have any problems even with a great fighter like Mayweather because of his supreme toughness and aggressiveness. Greb is perhaps the greatest of all time and would prove it too.
Greb TKO14 in a one sided drubbing!
Greb would destroy Mayweather.
Greb is arguably the greatest middleweight ever while Mayweather is 1 of the best superflyweights and welterweights ever [he has only had 3 fights at 154lbs, 2 against HOF both of which Floyd struggled so he isn't an atg in the division].
''A great big man will always beat a great little man''.
Aside from that; a great swarmer always beats a great boxer. Boxers win when they have control but a great swarmer throws punches in bunches which is hard for technical boxers to control. Gene Tunney, a technical lightheavyweight master, only ever lost to Greb, arguably the greatest swarmer ever.
Mayweather wouldn't go past 5. Greb didn't punch hard but for a natural flyweight he sure as hell did, and his volume would be too much
This is ridiculous. Do you know how far back in time Greb is. Modern contenders from this era at 154 would give him trouble. The time difference is more than half a century and Greb wouldn't get away with dirty tactics. These are the modern times, not the 1920's were you needed to be tough, fit, strong and fast to win a bout. Theres plenty more to that. Floyd would embarrass Greb. Too big a time difference.
Harry Greb, no contest here. Actually Greb didn't duck nobody. It's a shame to compare him with one of the most famous duckers in history. Let alone how Floyd wouldn't fight with these tiny little gloves they fought back in Greb's manly era simply because he would get KTFO.
Sorry to say that Harry Greb who beat Gene Tunney and other light and heavyweights in his time would have easily taken the 154 lb. Mayweather. Too rough, tough and unorthodox
Floyd wins. Maybe even by DQ, but somehow he'll find a way to win.
prime vs prime?
