His chin is a bit fragile to say the least, but so is Wlad's and Haye's, Khan could still become an awesome fighter and difficult to beat
Im impartial to this one, wouldn't say its solid but I think he's pretty much underrated. Fireman Flynn put Jack Dempsey away for twenty seconds early on in his career, and had that been during the glorious days of ESB, he'd have a paper stapled to his chin saying "Fragile".
It's more like that paper that Bounty always compete against in the adverts. [ame]http://www.youtube.com/watch?v=qL02SftjCe4&feature=related[/ame] That's Khan's chin 0:20 in.
