These are two the major names that come up when talking about about featherweight's hardest punchers. This isn't a thread about who would've won in a fantasy fight, who you liked more, or who accomplished more. Its about who you believe was the harder puncher.
I'd lean to Saddler, and that's no knock on Hamed who was one heck of a puncher. Saddler did it for a much longer period, against a much better quantity and quality of opposition. Saddler was Thomas Hearns with a nasty streak and a deadly in close game.
For raw power, probably Sandy. Naz's power came partly from the extraordinary angles he was able to create with his agility and utter self-belief. His opponents were devastated by dint of never seeing the punch coming as much as by the power. Sandy, though by no means orthodox, was markedly less subtle and needed the additional weight of punch to compensate for the lesser degree of surprise. His opponents knew what was incoming. Didn't seem to help them much.
The legend says Saddler, and I love learning about this guy, but the video evidence favors Games as there's just more to choose from
