Both guys get away with a lot considering they have poor fundamentals/technique and KO power relative to their weight class. Wilder in particular seems to have graduated Suma Cum Laude from the Luke Rockhold School of Sticking Your Chin Up After Throwing a Combination. Hamed at least had really good footwork, and had unbelievably powerful punches relative to his weight class(es). It took less effort from him to drop his opponents than Wilder does. Hamed had more skill imo.
