atsch I swear a god idiots on here think amateur helmet protects you from nuclear attack or something, you have a video of Tyson knocked down with headgear i guess he had glass jaw too, go in boxing gym and put fighting helmet on you will see your chin is wide open, does it help yes a little but not even close to what you fools think.
If Sergey would lose this fight .. i'd quit watching boxing forever. But yes, I see your point. Something so amazing and beautiful for the sport like Kovalev is almost too good to be true. I think he's the most focused fighter in boxing. I do not see anyone beating him for a long time.
