If GGG gets back into the ring with a young strong fighter at 37 after the last fight where he absorbed a lot of punishment he'll get stopped
I think Golovkin by KO is the most likely outcome, but I'm not confident. Prime GGG would easily beat Charlo, but the current somewhat faded GGG will have a problem with Charlo and may even lose.
Charlo gets put down to the canvas in embarrassing fashion. This fight is over in 6 rounds. What can Charlo offer? He's got power, but GGG has the best chin in the game right now. And skills-wise, GGG is light years ahead of this hypejob clown. He is Errol Spence's waiter, cook and sparring partner. He bows to King Errol of Texas and brings him food at the tea party. And that's all he does. He is a joke, and he will be exposed. Charlo shouldn't even be going anywhere near GGG.
