RIP for the guy. Another death for boxing, another day of mourning. What could be possible changes in boxing to avoid future casualties? Boxing is a sport for the warriors though. These guys know that death is always in play once they enter the ring either for a real fight or a sparring session.
I don't think we can avoid it, boxing organization is doing everything they can prior to the fight, test and everything to see how healthy the boxer is. Maybe reducing the rounds again? but it won't be as competitive.
When there's a boxing casualty, it always leads me to remember when a boxing promoter tried to stop the UFC from becoming mainstream. I think it was Bob Arum or Don King, calling MMA as a sport for barbarians and branding it as very dangerous and it needs to be stopped. Correct me if I am wrong but I haven't heard of any deaths or fighters in a coma in the UFC or in MMA in general.
Referee in MMA I would say is very sensitive of the fight, if they see that the fighters is slipping up, they stop it right away. In boxing it's different, there are a lot of misjudgement on them that could result in deaths in my opinion.
