We don't know if Ggg power will have the same affect at 168 lbs Abraham was a huge puncher at 160 lbs at 168 lbs he has been no where near as successful.
GGG would destroy him! Kovalev has been down a few times in his career, so a weight drained Kovalev would no doubt get kO'd
GGG is a monster puncher and Kovalev's chin is pure Russian glass. GGG knocks Kovalev out 1000 times out of 1000.
Even a weight drained Kovalev probably KO's GGG. You guys really are turning people off to GGG, weigh divisions exist for a reason for the 1000th time.
