Poor balance is just an excuse? Then why wasn't Manny knocked down? Why weren't they able to stop him? The point is every fighter gets hurt, but not every fight goes down or is stopped when they get hurt. Manny hasn't been stopped from a punch to the head or from taking to many shots. But of his stoppages which came when he was a teenager were body shots. But back to the balance, anyone that has ever boxed before knows that balance matters when you take a punch, if you don't have a strong foundation, when somebody hits you cleanly, you will be off balance.

As for Hopkins not having a great right hand or Roy Jones? What were they landing on Calzaghe? Did you see JOnes against Trinidad? He landed his right hand at will. Hopkins landed his right hand against Winky Wright, Tarver, and Calzaghe to great effect.

If you think you know guys with better crosses than Mayweather, Pacquiao, Hopkins, and Roy JOnes Jr then list them, I know the list won't accurate already, but you go on and list the people who throws better crosses.

Also sparring doesn't mean anything in terms of power, but it does matter in terms of speed, and power is the one thing Manny doesn't have to worry about, he hits harder than either Marquez or Vazqeuz. Also your comparable examples are terrible, Mayweather wasn't training when he sparred Spadafora, Morales wasn't getting owned by Valero, and we don't know how good Valero is, supposedly he was owning Oscar in sparring as well. He may be a lot better than his competition allows him to show.
