I apologise sincerely to the OP for coninuing this sidetrack of his thread

As has been pointed out, styles make fights. Mayweather's style allows him to move in up weight because his style is based on him doing two things:

1) Not getting hit
2) Landing alot of counters

His ability to do this allows him to outscore any boxer on the planet, bar none. He does not need a knockout, or even te ability to knock somebody out.
Personally, I view his style as somewhat similar to amateur boxing in a sense. (THIS IS NOT A DIG AT HIM IN ANY WAY) He scores points with the judges by landing and not being hit, however the effectiveness of his punches is much more than those of an amateur. As an amateur is, he is reliant on the technical aspect of the art.

The difference lies in the potential of opponents. Amateurs are rarely faced with brutal opponents who will leave them wondering what day it is. 1 punch is 1 point. With headgear and bigger gloves, you will feel a big hit, but you can always come back from it, land a few soft jabs, picking up 2 or 3 points and be ahead on the cards, even if, in reality and without headgear, you would have been seeing stars and counted out.

Mayweather's whole career is based on not getting hit. But guess what, one day, he will. He would hands down beat Hatton or DLH on points. There is no question of that in my mind. He is a technical genius. But, we have to ask ourselves two questions:

1) Does he have the artillary to stop them?
2) Do they have the artillary to stop him?

In my mind, the answers are yes and yes, ifor DLH and no and yes for Hatton. I put DLH at about 20% to win by stoppage and Hatton around 35%. I can see Mayweather stopping Oscar, but there is no way I can see him stopping Hatton.

I know I will probably get sad clicked for this, but it is just my opinion. Yes I am a Hatton fan, but I also respect Mayweather's outstanding ability. I'd actually like him as a boxer if he weren't a complete tool as a person
