RJJ was a lot faster than Mosely has ever been, had better reflexes, was more unpredictable [due to insane footspeed/work and his unbelievable ability to throw any punch from any angle] and hit a lot harder, and yet Mosely could probably have finished Floyd in round 2 if he had had the gas in the tank [let's face it, he clearly didn't - at least not on fight night]. The only way I can see this fight unfolding is with RJJ catching FMJ hard at some point, either resulting in FMJ not getting up, or being unsteady and then getting finished soon after - because RJJ put em' away whenever the hell he wanted to, and he would not only have had the ability, but the desire, to put FMJ away in his prime. Jesus, the man was an animal. Sorry, but even with all his technical skill, I don't think FMJ could stop RJJ. And even if he did manage to keep him at bay, he would lose heavily on points, a la James Toney.
