:huh Thats a tough one my mind says lewis had to punch harder,but on the other side you cant count out smokin joe
In terms of breaking down opponents it's hard to top Frazier. But Joe wasn't a top end puncher. Lewis was.
I think these two have different kinds of punching power. Lewis punched with leverage, Frazier punched with torque.
Lewis had a bigger single punch than Frazier. Frazier would just keep on comming forwards hurting his opponents with non stop bombs.
If each of them hit you as hard as they could, Lewis' would be the harder punch, however, Frazier hit hard with every punch he threw and Lewis did not. Frazier was the more consistant puncher.
