Ok, what we have to do :

Build an ultimate boxer. Assign attributes to create the perfect boxer from recent times. (currently active or active in last 5-7 years or so). You could build one from multiple nationalities, or a specificly British, American etc one.

These are the parts :

Chin :
Handspeed:
Heart:
Body Punching:
Jab:
Defense:
Ring Brain:
Power:
Accuracy:
Stamina:

So here is my British fighter:

Chin : Wayne McCulloch
Handspeed : Joe Calzaghe
Heart : Richie Woodhall (honourable mention to Woods,McCulloch)
Body Punching : Ricky Hatton
Jab : Lennox Lewis
Defense : Johnny Nelson
Ring Brain : Lennox Lewis
Power : Naseem Hamed
Stamina : Joe Calzaghe

That looks an impressive fighter to me. So go on, have a go. You could do a British fighter, American or any country you want. Or a multi-nationality one.
I could have put more catergories but keeping it simple, hence the jab is the only punch with its own section.
