Who had the hardest Left Hook in the Heavies?

[El Kabong]

Tyson was the best puncher, left or right hand that boxing has had in any division, period. Everyone just remembers him after he snapped. There isn't a heavyweight in history that would have been able to deal with a prime, in shape and focused Tyson's speed and power.

There are plenty of guys who would have whipped Mike's ass in his prime...here's a short list

Foreman
Bowe
Holyfield
Lewis
Louis
Frazier
Ali
Ray Mercer
