Well here is a list:

Relentless pressure - never gives opponents a moments breather

Quantity and accuracy of punches - many times throws over 1000 punches a fight and has success rates sometimes at 40%

Wears opponents down - is a bit like playing a fish - he makes them more and more tired and as this occurs he takes more and more chances, until they are so weak he knocks them out and they have no will to continue

A fanatical student of the sport - he has a deep passion for the sport and studies all aspects of it to the minutest degree - he loves the sport and knows tactics and details to the finest details, unlike boxers who fight purely for money (hence would inherently not like spending every second watching the same video 100 times)

A wicked body punch - he has finished numerous fights wth it

Excellent footwork, allowing him to throw punches from all angles, to feint and wrong foot opponents using split second gained to land own unches without getting hit himself too much - the times when he gets hit are often so that he can land his own punches which he has calculated will do far more damage

Will to win - feeling of invinciblility and destiny

Training - wicked stamina - when no training hitches he gets more and more brutal as the fight goes on

A good chin

Excellent boxing brain - he knows his gameplans before the fight starts

Thats enough for now !

I think it is very likely he will destroy Mayweather with body shots on 8th Dec, this is gonna be an awesome fight
