Not at all, its his own fault. He runs before he can walk. Hes way too cocky even when he has no reason to be.
He shouldn't be in a boxing ring, especially not right now.
People felt sorry for him after his first fight, did you see how he was 'preparing' for that fight? KSI was training consistently whilst little Deji was sitting on his backside playing games and eating chicken wings. Theres a whole vid where JJ tries sparring with him on his livestream and Deji is sitting there screaming like a girl and calling for help because his brother is 'bullying' him. No wonder he lost. Boxing - hell or just any fight - is more than skill. Its a mind game. You need to be ready for it mentally, physically, emotionally. You need to have the stamina for it. You need to have the backbone for it. You need to have the experience for it. Most fighters are athletes, you can say what you want about KSI or the Paul brothers but when they agree to a fight they put their heart and soul into their training, they dedicate their time to it. They don't just train for a few hours a week, its several hours a day. Deji can claim that he trained hard for this fight with Vinnie but just by looking at his body you can tell that he didn't dedicate **** to this fight. He wasn't in shape and TWO rounds later his legs gave way.
If he wants to fight again then he really needs to get his ass in the gym and train vigorously day in and day out for a good year or two before anyone takes him seriously. He'll need to stop making cringey ****ing videos every week. And he'll need to cut back on his cockiness until he actually wins for once.
