Could GGG have done that to KOV?

GGG wouldnt have the balls to fight at 175. So no.

Golovkin refuses to move up in weight at the age of 37, unlike Canelo who is a 4 weight division champ at the age of 29

it's all would ofs for GGG. All I know is that every time he steps up (all within his comfy 160) he looks good but not great. fantasy fight P4P

We dont know they didnt fight nor they would. I can tell you this though, how many times kovalev has been koed? That should make you rethink some scenarios

No he wouldn’t even fight him

GGG's output of power punches is high and Kova's defense is not stellar. Golovkin would gass him by round 4 and KO in 7

Better question to ask yourself is after boxing Golovkin for 24 rounds, and arguably getting 2 gift decisions, why does Canelo keep saying that Golovkin doesn't pose a challenge for him, while KOing Kovalev in 3 shots.

Yes - Kovalev was gassed after 6.

Probably yes. Kovalev has no chin.
