I know who Kotelnik is, but he didn't, like he probably didn't even know that Khan has faced and dominated Maidana at the same age Broner got dominated by Maidana. And beating Kotelnik can mean much or little, since he's been totally inconsistent in his short career.
The fact that Broner's chin is weaker than Khan's is irrefutable. Hence, it is glass or even toilet paper level.
How come Broner's chin didn't fail him against Maidana? You have no answer. You can't answer this question without sounding like a moron, lmao. Men have been ko'd by lesser punchers than Maidana. Broner was put down and wobbled multiple times by Maidana and yet he lasted all 12 rounds. Khan tried his hardest to get up from Prescott's shots and couldn't move, yet took Maidana's shots. Why is it that Khan looked he was like he was paralyzed against Prescott, and took Maidana's best. You guys pick and choose who to hate on, and you can't even do that right, lmao.
