The only advantage blacks have over whites in boxing,and this was mentioned by another poster,is in the cut department.Whites have more of a propencity to be busted open than do blacks.As far as cranium structure goes,well there have been plenty of whites who can take a good shot,in fact there have been so many that you can't say it's just another exception to the rule.The best examples I can give are Billy Graham and George Chuvalo.These two guys had a kajillion fights and neither one tasted the canvas.Yet there have been plenty of china-chin blacks who didn't take a good shot like Tommy Hearns, Earnie Shavers and Floyd Patterson.It would be interesting to know just how many times Floyd was dropped,I'd say it has to be close to twenty.I don't about blacks having longer arms,but that doesn't make you automatically better because of reach advantage,there are ways to get around that.Once again guys,it's socio-economics that have kept blacks and hispanics in the limelight,there is that desperation factor that whites don't have because plenty of whites have other options and a lot of blacks don't.Although the Eastern-Europeans may have something to say about that.
