Gonna go historical just once....Joe Louis infamous Blackburn Crouch & Rear Hand Parries...!!! There may be footage of this on YT, I didn't look yet...!!!
Floyd Shoulder parries well, that goes without saying. young foreman would paw hands away if we are counting that. holyfield fo sho. Kllitchko
Foreman was surprisingly good at parrying. More of an aggressive parry in that he'd actually appear to jam the opponent's lead with his rear hand. Pretty effective tactic.
RATJ comes to mind. Ali no doubt imm used it against foreman the most effectively against anyone in his career.
Like mentioned earlier, Oscar didn't like using too much upper body movement, so he became very good at swatting punches away. Floyd is very good at this too, tho he very much prefers rolling with the punches.
Yeah, plus he negated Foreman's parrying technique by using the right lead more frequently. Ali's performance in the Rumble is pretty underrated.
