Amir Khan is the very definition of glass jawed, he's been hurt or dropped by almost everyone who he's shared the ring with that's half-decent. Yes, he has blistering hand speed, an solid back foot game, throws amazing combinations, and has heart. Talent-wise, he's world class, but that one drawback he possesses, it's one hell of a humdinger. His chin isn't just bad, it's transcendentally awful, like journeyman or gate keeper level horrendous. Let's see..... Breidis Prescott KO'd him with the first flush punch that landed. He was rocked to his core and dropped fairly hard by Willie Limond of all people. Rachid Drilzane clipped him, causing Khan's glove to ouch in the 7th, yes it was legit. He got viciously dropped and later badly rocked by Samuel Vargas. He was dropped and stunned by Julio Diaz. Dropped three or four times by Danny Garcia and stopped. Knocked unconscious by Canelo Alvarez. Bullied around the ring and beaten up by Lamont Peterson. Was put on queer street by Chris Algieri of all people, and arguably drew with him. Was battered from pillar to post by a badly gassed Marcos Maidana, who he should have lost to. Oh wait, there's also this. Okay, on to Jorge Linares, he's been stopped 5 times, and of the five times he's been stopped, three of them were from legit KO punches. The other two were TKO's caused from cuts. Now, onto his skillset, it's immaculate, his hand speed and combinations are a thing of beauty. His footwork is splendid, punch placement is next level, all around he's one of the best pure boxers the sport has to offer. But, he also has a drawback, the chin is a little fragile and tends to let him down occasionally. But not as often as it seems. His stoppage loss against Antonio DeMarco was do damage to his nose, which was practically falling off of his face, and had been for about four rounds. Anyone who holds that TKO against him is kind of a ****head. Then there's the match against Sergio Thompson, Sergio jumped on him in the second, swarming him and busted his eyelid open, fight stopped by the doctor.. It was right after his match against DeMarco, clearly he returned too soon. He got KO'd by Juan Carlos Salgado, who at the time was undefeated heavy-handed very good fighter who cauht him cold in the first, a Jack-Edwards type deal Recently he got KO'd in the first round by Pablo Cesar Cano, while in theory that should be shameful, but you have to remember Jorge started out as a bantamweight/featherweight. Cano is a huge light welterweight who's competed at welterweight, and is one of the few guys the drop Paulie Malignaggi something Broner couldn't do. He was dropped by Sotelo and Mitchell, but managed to get back up rally and stop both of them. And that brings us two Lomachenko. Like with Khan's KO loss the Canelo. No big deal there, although Linares lasted longer, and the KO was far less brutal. So honestly, aside from Linares being mentally tougher, what is the difference?
