GGG can be knocked out with a straight right hand to the body quite easily. He does not guard his body when he is setting up on the ball of his forward foot to throw a left hook. Half of his rib cage is exposed on his left side. A guy like Roy Jones could anticipate that left hook being set up and fire a straight right hand punch underneath GGG elbow and it would be a spectacular knockout. One punch. The problem is nobody has balls to stay in the pocket with this guy and not to take a step back. No one will beat a guy like this if they even take a single step back during the fight because that single step back could be your last step before you are counted out. Somebody has to be in his face pushing him back like a Marvin Hagler or a Rocky Marciano type of fighter. Only a pressure fighter will beat this guy. A boxer will not win and neither will a boxer puncher. And Aaron Pryor type fighter can beat him and has to have enough pop to throw that right hand to the body when this guy telegraphs that that left hook is coming
