Re: punch through
There's different kinds of hard punches. Sharp precise ones (Mayweather), ones that catch you moving into them or clip you (timing), crushing ones that just overpower you(force/strength...Tyson), snapping ones that kind of have the baseball-off-the-bat effect (SRR-Fullmer), etc. Then there's guys like Arguello/Monzon/etc that just have a heavy-handed sort of power that feels more damaging when it lands. So just hit the guy somehow.
