Mosley easily, Hopkins should beat Jones with a pack of 5 year olds training him. Mosley on the other hand might need every trainer in the Continental US to help him against Mayweather.
Shane obviously. RJJ is done and everyone knows this fight is a farce. Plus look at what it would do for Nazims legacy as a trainer if he's the first one to figure out how to beat Floyd.
Strategy wise and conditioning wise Mosley definitely has more of his work cut out for him. Plus Mosley is a new fighter to him and he has been with Hopkins for a longer time. Hopkins has a lot of his plan in his mind already, I mean he has been thinking about how he would fight Roy differently for the last 14 years. Where are hopkins-Roy fighting? If its Vegas or Cali that would be easiest. I assume they will both be training at big bear so it probably wont be that bad. Maybe Hopkins can do some light sparring with mosley imitating Roy jones even, that would be interesting. idk why but that was so random
