Just watching GGG-Stevens and Lederman, in a rare moment of clarity, said GG was an accurate, come forward, punching machine. This got me thinking about Joe Louis and I see some similiarites between he and Joe Louis. GGG has a ramrod jab that he uses to push his opponents back and open up their guard. He doesn't move a lot but maintains fantastic balance as he inevitably and patiently moves forward. He doesn't look for the knockout but allows it to happen. However, when his opponent is hurt, he goes for blood. Every single punch, even that jab, is designed for power but thanks to his amateur career, maintains tremendous technique.
Sounds like Louis to me...
