What about Holyfield on the end of a jab. Sure some of the heaviest jabs at time..Foreman, Moorer, Lewis, Bowe but among a few who caught him flush and buzzed at one point or another. Just rewatched Stewart and even a Rodriquez stick him repeatedly before the end came. Probably Mercers best punch against him really.

Salido- Rules
Norris- At times mistook sitting or downed fighters as still six foot tall and hit them in the head.
