Some guys had a delayed reaction like holy **** what just hit me, the opponents face says it all and i reckon he could probably do away with george chuvalo
Shannon Briggs said Vitali (who was at this stage, an arm-puncher) hit him harder than Lewis or Foreman did.
Archie Moore said Patterson hit him harder than Marciano did.
For a more recent example, Mosley said Canelo and Mayweather hit him just as hard as each other.
There are so many factors going into that type of opinion that you don't even need to register that they are literally being punched in the face when they form that opinion.
Foreman bounced around bigger men, and much better opponents than Shavers. His grazing blows would push big men off balance, but you can't say the same of Shavers.
