Who had the better good chin and cardio: Kamaru Usman or Georges St-Pierre?

Usman doesn`t have a great chin, GSP never got sparked by one kick the way Usman did v Edwards.

 

GSP is the better fighter in most ways but GSP was very chinny, I don't believe Usman would get KO'd by Matt Serra.

 

Usman has a better chin and you could argue cardio but GSP was the better fighter.

 

GSP proved his mental toughness and chin on many occasions. Usman’s chin was never really tested until Edwards cleaned his clock. I don’t think Usman would’ve survived a flush headkick to the temple from Carlos Condit or the early barrage from a roided up Johny Hendricks.

 

Ali had a better chin than both of them.
