I think all of you overlook a very important factor in here............... Olympic Games.
Boxing has always been a white dominated sport, even in the 60's, 70's and 80's that blacks were supposed to dominate the local American Professional boxing scene, since in 95% of the cases, the boxers who competed for the titles in those eras were Americans regardless race.
At the Olympics where the whole planet had "free" access, Eastern European nations were winning 60-75% of the gold, silver and bronze medals, it's a plain fact.
How do you expect a Soviet, a Polish, an Eastern German, or a Hungarian, like the greatest amateur boxer of all time, that Laszlo Papp is, to beat at the pros an overrated black American that he already smashed as an amateur, when these guys were winning gold medal at the Olympics but had no right or chance to even turn pro, thanks to their communist countries?
Oh and by the way, the best Negroes in the sport are not the overrated and over hyped Americans who failed at the Olympics against real competition, the best Negroes in the sport are the Cubans, FACT!
African-Americans, the vast majority of them, during their over protected professional careers fight in their backyard exclusively, have the mafia to protect them, anti-white promoters like black panther Don King and Jewish con artist Bob Arum, corrupted judges, corrupted referees, fight in front of their fans in most cases and still once the Iron Curtain did fall, they get beat from beasts from the east.
