I just watched the highlight of their fight. it was fun and entertaining. to be honest, with a decent coach I can see hafthor becoming a decent boxer if he continues his training. you can clearly see on the fight that he is using his reach and height advantage(though still sloppy) and actually throwing the left and right combo.
Well, one of the characteristics of boxers who are tall is to have more vision of how their opponent can react when they are shorter, and having long arms is clearly an advantage, the only option that Hall took that I liked is that he knew move but he was not fast enough to attack Thor's back and ribs, when a boxer is shorter he has to concentrate on the easy targets and not try to try harder to be at the level of a boxer who outclasses him. height, I think Hall lacked much more desire. I know that in contact sports, self-esteem is usually something that can be easily lowered, perhaps that explains the reason why every athlete needs a psychologist, the morale of every athlete must always be sky high to quickly find solutions when everything gets complicated.
