Gennady "GGG" Golovkin has had better offensive fights (he landed and average of 20 of 65 punches per round vs. Adama), it was his defense that was more impressive, as the challenger landed just 12% of his total punches.  Adama had his moments in rounds four and five, before foolishly opting to brawl with GGG, who landed a fight high 21 power shots in round six.
