It seems like a lost art in boxing. I think the main reason Manny has maintained his speed is because he hasn't become flat footed. We saw Roy JOnes Jr and Mayweather slow down in terms of their bounce IMO because they prefer to have their feet solidly on the ground. I think Oscar wasn't able to come forwad like he did against Mayweather because Manny is always on his toes, he was able to come and get out so far that Oscar couldn't counter him at all. He didn't move as much, but his footwork reminded me a little of Leonard who use to love to stay on his toes. I wish more guys would still do it.
