Foreman had genuine world level KOs, both in his first career and in his return.
Shavers comes in second based on the testimony of all those that faced him. Tyson could be second too, or at the very least, 3rd.
Not sure how or why Wlad is getting a mention.
I'll have to say Foreman. Tyson was a devastating puncher but Foreman was effortless.
Yeah, why is Wlad on here?
This. Foreman was effortless, no leverage....his jab alone was powerful to stun opponents. Heavy heavy hands.
