http://bleacherreport.com/tb/b8Jg6 just saw this footage of spad v mayweather sparring from 10 years ago and he certainly holds his own. can't say i've ever seen him fight although seen his name bandied about plenty. he looks like he can do a bit to me...
He was too busy shooting his girlfriend and crashing into police cars for his career to make any real progress, although he did fight some decent fighters like Manfrady and Sosa.
To answer your question, because he was a bum himself. Once he got in the ring with a decent boxer(Leonard Dorin) he was emberesed and got the home town Split Draw. SO....HE WAS NOT THAT GOOD AT ALL:good
Bums can't slap the **** out of Mayweather in sparring. I don't give a **** what excuses any Mayweather fan comes up with... Spadafora laid it on him. Everyone here knows Mayweather is a gym rat, so he is always in shape... everyone knows how serious Mayweather takes his sparring, and how he prides himself on in sparring sessions. NO BUM can hand Floyd Mayweather his ass in a sparring session... hell a bum couldn't even almost hold his own against the likes of Floyd.
