Lol i hate the fact when a fighter has power, people don't credit his other attributes. GGG was an amateur world champ and olympic silver medalist. check out these beauties againsts a cuban. https://www.youtube.com/watch?v=cNSBqp5oW5A https://www.youtube.com/watch?v=atKApcCFEug Its like people who say Tyson only had power.
As you may not know, Kovalev is in Russia nowadays. He gave this interview today and as Krusher sparred with GGG, the question was asked on whether GGG's power is real/overrated/a myth? Kovalev: "Not a myth. He hits even maybe not like a lightheavy but a heavy, I can't say for sure. Gena hits strong, quick and stiff. I can't say how to compare power of a middle/supermiddle/heavy but when he lands his shots on you, you feel damage on your body. In sparrings with him your self defense mechinism starts working at 100% and you get cautious and attentive. Off course when I came back from Russia untrained I could not work with him at 100% but later when I gained my form we had pretty good sparring sessions where we hit each other like mules, anything could happen in those sessions, I got hit, he got hit. That's it " Souce: https://www.youtube.com/watch?v=-6TVWqM3prU&feature=player_detailpage#t=415
Bro thats the amateurs, its a points system game. His technique, balance and precision is great for the pros imo. Not even mentioning power. His D could use work but again i think its due to him being too confident in his power.
