I was rewatched the DLH/Vargas fight yesterday and I noticed George Foreman making a lot of derogatory remarks about Floyd Sr. During the fight he said something to the effect of "Oscar needs to get back to his old trainers", and after DLH got the knockout, George said that "it would have happened a lot sooner with a different trainer."

I was just wondering if anyone knows if Foreman and Mayweather Sr have some sort of bad blood? George stated these things in a "professional" manner but it really came off as him having a grudge against either Mayweather himself or his training methods.

Any boxing historians/experts have any tidbits of info you could give on this?
