Boxers and Hollywood using concussive shockwaves

I thought id have a little look at some boxers who are known for there power and more importantly how there strikes felt,Like foreman says he could feel it through the guard,these are punches using shockwaves

and a clip of George himself who has excellent kinetic chain and a very nice shockwaves in his punches

Here's a top ten list look closely and see which ones you think have the best shockwave?

and heres and interersting angle and a bit Hollywood v reallity, but again the hardest strikes would be the ones with the sharpest shockwaves and the ones where it only takes one clean strike.
