Kovalev has been dropped before both as an amateur and as a pro, GGG has never been dropped in his life.
Garcias chin is glass compared to provodnikov ruslan took 100 plus flush shots from lucas without backing up or holding or resorting to low blows Garcia took most likely took 3 max flush shots and wobbled each time Ruslan was walking through shots all night Garcia was backing up and took way less shots and wobbled
Everyone on that list is proven by fighting top notch opposition. Who has GGG proved his chin against?, tomato cans he exploded into the ring against as a 200-1 favorite?.
Luis Ortiz Ruslan Provonikov Terrence Crawford Robert Guerrero Sakio Bika Sam Soliman JCC Jr. Steve Cunningham Bermane Stiverne
