not sure about that,... when ur a heavy weight they cant do alot of the things that we see these lighter guys doing. i mean they run out of breath faster, not as agile, and kind of move slow... but that dosent mean there bad fighters, it just means there big/fat
...and since its HW, there alowed to be like that. well because of that the fights may not look as interesting or a great fight, but for the fighters its a whole different ball game of tactics.
oh, and if ur looking for a good HW fighter.....
