It's his skillset above all else. He didn't have the athleticism and physical attributes to keep up with Bradley and Floyd. But his skill, the footwork, punch selection, timing, strategizing is amazing. Then comes his toughness and warrior spirit. Then killer instinct.
He is a beautiful puncher,the way he sets his shots up are a thing of beauty...and when you hurt him in reality you really hurt yourself..
Pinch variety and desire to punctuate exchanges Always seemed like he and Pacquiao competed for the last punch Each guy wanted the final say and that's why those fights were so good
