Fortunately for you this isn't prime iron chinned Ustinov. The guy went like 20 years in boxing/kickboxing before getting dropped.
Joyce has zero explosiveness. Every shot he throws looks more like he's trying to push somebody away with his fist.
I was convinced Joyce beats Dubois/Gorman handily...Now I'm not so sure. He's such a weird fighter. No discernible skill apart from throwing alot of punches and having a good chin?
