I hate when people say margarito sucks when before mosley fought him margarito was the most dangerous man in the WW division? That being said I always felt margarito was way overrated, especially by boxing fans. However you cant just jump off the bandwagon when it suits you. This is the same with Mosley. Mosley cant be the best WW out there before mayweather fought him and then be Shot after mayweather beats him.
Hooking up with Nazim was the key that rejuvenated him. Jack Mosley was not a particularly good cornerman for Shane. He never knew what advice to give when things weren't going Shane's way. Far from the case with Nazim in his corner. I honestly believe Mosley's father had a prodound negative impact on his career which culminated in the Cotto fight.
dude, watch shane at lightweight, his first few fights at welterweight, de la hoya 1... he always had fast hands. he just started to slow down as he aged like roy jones. The difference is that shane has more fundamental skills than roy jones, although some may disagree. vs margarito, he just looked as fast as he did when he was younger bc he had an easy target in front of him. Also, i believe that when shane moved up to welterweight he did a lot of weightlifting, and recently stopped. The weightlifting idea is just a theory. I am not sure if he will be able to repeat this against floyd who is much harder to hit. But to answer your question, if you properly watch shane's old fights, HE ALWAYS HAD FAST HANDS, that is how he built his reputation in the 90's and early 2000.
