In addition to that, nobody recently has really maintained a consistent enough offense to discourage or outpoint Manny while moving to the right.
Shane, Bradley (moreso in the 1st fight) and Algieri all did the whole move to the right thing yet still got hurt/hands put on them.
Floyd's best bet is to step in with the right hand first and try to time Manny before he moves, but that's still pretty difficult since Manny is quick and has great footwork. Morales did it, but he wasn't afraid to get hit. Manny doesn't cut off the ring, but he still pressures you into fighting to keep up with him. The lateral movement does nullify Manny to an extent, but most aren't able to sit on their punches or throw enough to really win while lowering Manny's volume. It's like you gotta attack Manny while also trying to outbox him. Floyd has the ability to do that, but...
Floyd under his father ain't throwing any real hard shots anymore and he doesn't throw combos like he used to. However If anybody could beat Manny by moving to the right and throwing only one shot at a time while somehow not allowing Manny to outwork them, it's Mayweather, but the judges might not like it as much as the purists do.
Damn, I'm really starting to get hyped for this fight.
