Wlad's chin has never been an issue. Wlad's problem USED to be that he had absolutely no idea what to do when he got buzzed. It happened so infrequently that it was almost complete shock when it would actually happen. This is why Manny Steward forced Wlad to spar for so many rounds in preparations for his fights. Now Wlad is more adept at taknig punches, fighting tired, pushing through... thinking his way through while fatigued, learning how to pace, and how to properly go on defense when you need a break, ect... These are all things that Wlad lacked before when he was just steamrolling everyone. Wlad learned from his mistakes, learned from his new trainer... and now isn't anything like the fighter that we used to see. He doesn't blow his wad throwing so much heat from the opening bell... even when it wasn't there. He doesn't overextend on his shots, which got him in trouble earlier in his career... and he doesn't get lazy when taking his backward steps after engaging anymore.
agreed plus 2 of the stoppages were him running out of gas thats why he is more patient in there and doesnt bomb guys out like he used to plus he has never been out cold he always got up
