The man is scoring some impressive KO's off of single shots and very early. His KO over Looknongntov was one of the best of last year. He has a 96% KO ratio which is higher than any champion I can think of.
Aside from Edwin Valero In terms of p4p power, I think he ranks in the top 10. As just an overall puncher (technique, variety, quickness, accuracy, power), I think he is outside of the top 10.
