I thought GGG looked a bit fleshy too. I'm wondering if we will ever see him at his best. All we have seen so far is him beating people up. People he knows he can beat up so he's taking liberties with his chin/defence. I've thought for a while that a fight will come along that will showcase him in full flow. If enough time passes and he loses half a step his whole career might be a series of brute force beatdowns.
