GGG already destroyed Kovalev in sparring, they should have part II in a bout, GGG stops him late on I think, Kovalev right now is on the decline
Prime for prime its not even a question I think. There are separate weight classes for a reason. A prime and focused and sober Kovalev would piece GGG up and posterize KO him early to mid rounds. Come the **** on, GGG is even small for a MW. Sparring is WAY different than an actual fight. End the **** of.
