He definitely had amongst the best chins but I was always of the opinion that Hrgovic's was probably better. Had never seen him be dropped or hurt, as a pro or amateur, and had heard some testimonies about his chin. Joyce had a great chin but he'd been stopped in a round before in the amateurs by Sergey Kuzmin I think. And while amateur stoppages don't necessarily mean a fighter will be weak chinned in the pros, Joyce was like 26 when it happened so it's not like he was an underdeveloped teenager like David Tua for example when he was stopped by Savon.
Not sure why Parker is getting hyped up so much now. The Wilder he beat wouldn’t even beat Chisora and he was only beating Zhang once his old man cardio became apparent.
People forgot that Joyce got done in the unpaid ranks. Careful matchmaking made the casuals think he was packing granite. Turned out to be a poppadom instead.
