Look at the torque on that left hook in the second gif. This man has seriously debilitating power that people that face him have to fear his punches.
(I do not take credit for the creating of these gifs. They are the property of notsuperstitious. I do not have the programs to make gifs as of yet but hopefully will soon so I can make my own and not use others but I will say if you do like boxing gifs follow that blog because they make some of the best out!)
