I believe the stability issue is a real concern -- I always hearken back to Gerald McClellan's ill-timed split with Emmanuel Steward (over money, I believe) -- but Floyd Sr himself does not impress me a whole lot during fights. His push for a KO against Adamek is just one example. I didn't agree with it at the time and almost got proven right.
Mayweather is a good trainer, he is probably expensive too. He looks sscary and he looks like he says a lot of crzy stuff too lol Chad is a young fighter and probably thinks he has learned all he could from Mayweather Sr. i think it will end up coming back to haunt him.....Maybe like September 29 or something like that HAHA
