Wrong SK3000. Trouble was - Hamed was that good but wasn't tested sufficiently before fighting Marco, and was probably on the slide. Most of the opponents were decent enough but not bonafide elite's like Marco. He split from his trainer and mentor, Brendan Ingle, and spent too much time listening to his brothers, who were nothing more than freeloading off him. He also went to Manny Steward (whom I admire), but was totally the wrong kind of trainer for Naz! If he had his time again (which he clearly won't) I would imagine he would do most things very differently, focusing more on boxing than trying to be Mr Big and pissing off genuinely good people who tried to help.
Why does he have to move up in weight? Oh, and Hamed was the little guy, who was really a 118/122 pounder but moved up in weight to have more marketability. He was knocking guys out that were so much bigger than him.
Paul Williams was a champion in his division and only has 1 loss. Chad Dawson is one of the top light heavys right now and is a champion.
