You can train your boxing, you can work on your wrestling, you can become a wizard at hitting submissions off your back, but the one thing that you can’t learn is the ability to land an explosive right hand and stop any fighter in the world in their tracks.
There are ways to improve power, but the guys who can put anyone out by throwing one solid shot to the chin are a different breed of being. The raw power that these seven fighters have is something they’re just born with, and no matter how hard you try, it is impossible to replicate.
The inspiration for the list starts it off.
