Khan has said he'll skip ramadam if he gets the fight vs money.
In all fairness, it has nothing to do with height and reach, styles make fights! Khan has all the tools to worry Mayweather. You say that he took Left hooks and straight rights all fight long, let's not forget that Algieri beat Provodnikov, it's not case of Khan weakness, Algieri is a great fighter, no fighter could avoid those lefts and straights all fight long. Yeah he'll get hit but he was not wobbled once, he took some bombs and stayed fine. Furthermore, Algieri is a bomber, if money were to come out swinging like that... well... money wouldn't come out swinging like that, never has, never will, and that's better for Khan... Styles make fights...
If you wouldn't say Khan's chin is good, then with all due respect you don't know shit about boxing. Khan did not know what to do when he is hurt, that is the difference, he's taken shots that would crumble many, but because he doesn't know how to react when he's hurt, he fights and he gets knocked down again - the general public see's this and "OMG glass chinned khan lol easy knockout cant take a punch".
I emplore you to actually watch some of his fights. To stay in against Maidana and actually BEAT him demanded a granite chin and a heart of champions, let's not forget that Maidana beat the fuck out of Broner, no one says he has a glass chin....
Yeah he got knocked out against Danny Garcia but i'd reiterate, he was with Freddie Roach who was toxic for Khan, how can you fight on after taking a Danny Garcia left hook (which has knocked EVERYONE out when he's landed it... watch... when your coach doesn't know what to tell you... now he's with Virgil Hunter, he's not gone down once, what more proof do you need. (bar diaz, who he got back up and dominated, because his chin is very good)
Khan, was the only one who took a Danny Garcia left hook, got up and kept fighting for more rounds.
There is more evidence for god than there is for Khan having a bad chin, it's just once a year boxing purists who decided that.
(also thank you for an actual discussion about boxing, I never get to debate with anyone anymore )
edit: I would also ask, have you heard any boxing pundit or expert say Khan has a glass jaw? It's only ever that guy in the pub who heard it once and thinks it's gospel.
