is that when he was fighting after the second marquez fight and going up in weight, what really struck me is how he changed. Not with his body, not his speed, not even his power. What I saw was a new PAC, he's footwork, he's improved right hand to throw diff combinations, basically how he fights altogether. He's improve in every aspect of his game, he's already perfected his style of fighting, going in and out, using his strong lower body lunging to attack, as well stepping back to defend. What Im saying is, does PED improve fighting skills?
