I like it but if it happens at 168 unless Golovkin moves back down which is risky it kills the claim of being undisputed and breaking Hopkins' record.
That would be great fight for golovkin go upto 168 beat Gilberto come back down and unify 160 if he could do that he would be revered as a god.
BTW for those who don't know, Bob Arum is just getting free publicity. He knows that there is exactly zero chance of this happening.
Except 1 more win @160 he ties bhop two and he has the record... which in the long term may mean more.
