I was wondering that as well. Either Conor has a low genetic ceiling in the stamina department or he filled his own head up with the whole BS of knocking Mayweather out quick and just did the MMA bare minimum cardio routine.
Canelo vs GGG is such a clean matchup. Canelo has great punching power and decent explosive speed. His main advantage is his boxing experience, he’s faced many notable opponents and learned a lot from them.
GGG possesses phenomenal power, has great ring control and stamina. He is a bit on the slow side movement~wise and uses his powerful punches to do the talking and set the pace for him.
I think it’s anyone’s match, but I give Canelo a slight edge because unlike most other boxers GGG has faced he will have to respect Canelo’s power and won’t be able to just swarm him as usual. That and Canelo is technically more sound so if it does go the distance I’m sure he’d win via points.
