I don't believed that 3 rounds is just enough for these great fighter who were hungry for knock out punches.
For the sake of humanity they are over 50 years old and going for a 3 round fight is a huge thing and they are not doing it to make money for themselves but to donate some to the charity.
Their defense is very tight and safe for each of them, and I don't think that shorter rounds can beat that eagerness. Hopefully that money raised for the fight will be enough to help to those in need of charity money, to help the affected individuals with covid cases.
Not just the defense both are the most talented fighters of their generation and i doubt apart from Tyson Fury none of the boxers in the present generation would stand a chance when these fighters were reigning as champions.
I still remember the Tyson vs Holyfield fights and they were horrific to see the second fight but the funny aspect at that time i thought Tyson was talking in the ears of Holyfield but at a later time we found that Tyson bit his ears and the total commotion which was scary.
