34-0 with 30 ko's including Taylor, Zertuche, Miranda and other tough fighters. Looks like better than good power to me.
He has power. and he has great knockout acumen. He put Zertuche in the sleeper. His powerhurt miranda and he eventually finished him off. His power hurt taylor and he finished him off. His power decimated lockett easily in 3 rounds. so i think its a bit of both but he def has power
Don't forget Taylor either....he was snoozin and had to be slapped awake..afterwards he clearly said "I got knocked out?"
Personally I think Bronco McKart settled this issue a few years ago: "It's not that he hits ya that hard, it's just that EVERYTHING he throws has somethin' on it," said McKart after suffering his first ever KO loss. As far as KP looking good at 18, the kid started boxing at age 9, and sports an amatuer record of 89-9.
