Come to think of it Manny did'nt need roids to improve himself so much

For the most part, Manny's improvement after the Hatton fight has been mostly technical. I mean Manny is just as fast and just as strong now as he was in the Hatton fight. He's just improved so much as a technical artist over the past 2 years. About the Cotto fight, and how Manny took Cotto's punches so well. We've heard stories of Hamed (a featherweight) rocking Middle Weights with one punch in sparring and no one complained. Why can't we have stories of a Junior Welterweight having a strong enough chin to withstand punches from a Welter-Weight? Pacquiao - Cotto anyone? Duran took some of Haglers best punches and he wasn't hurt...no one complained about him. Only time he was K.O'd was when he took a flush punch right on the chin against Hearns. Why can't Pac not get hurt against Cotto (who doesn't have a Tommy Hearns like punch) when Cotto didn't even get Pac on the chin? Flyod Sr. seriously just had to find an excuse to make sure his boy doesn't lose an 0 on his record. Besides, this is the same guy who said Hatton would PWN Pacquiao lol.
