Joshua has never been starched out cold like Whyte.. Against a 41 year old fighter at the end of his career - resulting in what most called KO of the year. Whytes chin is pure china. Joshua's is bad but but not the worst.
It's amazing that guys like James Toney or Oliver McCall were basically impossible to knock down never mind knock out.
I have inserted all of the relevant info into my science machine Whyte has fought Povetkin - sparked him AJ - knocked him out Chisora Parker - dropped him and almost stopped him Rivas - dropped him Helenius - I think he rocked him IIRC Wach Browne AJ has fought Wlad - dropped him heavily Povetkin Parker Fat Andy - dropped him x 4 and stopped him Pulev Takam Martin Breazeale And the results seem to indicate that AJ has the better chin
I'd say Whyte has a better chin but he's easier to hit. Joshua doesn't get hit much but when he does he turns into a zombie for 10 minutes.
Whyte seems to have the worse chin but he's also easier to hit. Joshua has a bit of Bruno in him, like when he gets hurt he covers up and moves back in a straight line , tbh that isn't a common occurrence but was more evident in the first bout with Ruiz, where Ruiz jumped on him with the relentless combos.
