Type of fighter: he is a very focused stalker puncher, he thinks, reacts, counterpunches and changes his style. His timing is great, he was better in tradings against fighter, who was considered a better and faster boxer. Power: beyond A+, all his punches are crushing, both hands, short punches, everyting... Btw he dropped some big guys in amateurs like Usyk. Punch variety: A+, he throws everything, crosses, uppercuts, jabs to the body, short punches, i saw him jumping and punching a la Pacquiao, lol Chin: solid A, i have never seen him being really hurt, but he was knocked down, so i am not gonna give him A+ Stamina: A, due to his style, he doesnt waste energy for unnecessary movent. Some people doubted his stamina cuz his fights were always short, but last fight proved that he is able to throw combinations of power punches in later rounds. Ring IQ: at least B+, this is hard to tell, his power helps him a lot, obviously, but he was a top amateur and a better boxer against Gvozdyk, more precise and effective. Now to Gvozdyk: A very good fighter, would probably beat anyone except BTR, but he needs another trainer. Atlas is just a coach for moral, you can have him in the ring corner, but you need a real coach who can give you technical and strategic advice. Coach who prepares you well for a difficult fight. And as bonus a scorecard: https://imgur.com/mbHGDJE
At this stage of Gvozdyk's career there is not much more you can teach him. These guys have an extensive amateur record and a lot of muscle memory so they always revert back to type OG looked nervous at the weigh in yesterday too in the face off. That's when I knew he would eventually crumble.
