Hopefully Dong doesn't rely on it. He fought like a crazy person last fight. It worked out then, but I don't see lightning striking twice. Especially against better competition.
He is one of the hardest hitters in the MMA world PERIOD.
Brown was focused on not getting hit to the body for the most part and favors volume over power in one shot, especially last night.
Dong threw all his weight into a full power punch. I'm sure Kim is one of the harder hitters with that judo strength and athleticism. Probably not "the" hardest hitter though.
