(1) Don't weigh in the day of the fight. Weigh in. Re-hydrate. Then fight.
(2) Stop the fight when the fighter can no longer intelligently defend himself.
(3) Dude died because of poor regulations. Not because boxing is as lethal as MMA. My argument wasn't boxing isn't lethal. My argument is that boxing is not close to being as lethal as MMA.
In a real fight, somebody can try and do this to you, if you are a boxer and you don't KO him with the first few punches, would you like to get smashed like this on the concrete?
