I don't think he's chinny (which, to me, means having a poor chin), but is just average. More than his chin, I think his recovery time is the bigger culprit.
I think some people lump this in with chin, but a clear distinction should absolutely be made between punch resistance and recovery time. It would take a very hard hitter to rock Rafael, but every time a hard hitter catches him he will be in some degree of trouble.
Both guys got hurt few times Israel did not looked very good bleeding from both eyes the difference was his recuperation and think Raf forgat his jab let's see what kind of adjustment in the third fight.
izzy does seem to have a better chin than rafa. in their two fights, it's 3-0 in KDs in favor of izzy.
