Ngannou is a bit of roided dosser. Yes, he punches hard, probably not as hard as Wilder, but whatever.
Doubt he's anymore roided than Wilder and probably less than Fury. Drugs or not he has a massive frame and spent years digging sand pits in Africa, that's going to give you strength you don't get at the gym. You have to punch harder to get results in 10oz gloves than 4oz but Joe Joyce complemented his power when they sparred.
Oh, yes, he built his body by digging sands, then he was homeless in France... Very touching story. Fury never looked roided, but I consider all professional athletes having used PEDs more or less. But Ngannou lived on that for years, I am not saying he was not naturally strong.
No, Francis`s boxing skills are awful, Wilder has thrown and landed more jabs, his 1-2 is awesome and he knocked Ortiz, Francis wouldn`t have landed a punch on Ortiz.
Francis would have taken Ortiz down and smashed his head through the canvas inside of 5 mins. Boxing is one aspect of fighting.
Wilder hits way harder, he's proved that in a boxing ring with 10 ounce gloves. This shouldn't even be a debate.
