I think this would be an interesting fight. Khan only really has one weakness, his chin. And Paulie ain't testing that, so could Amir pull off the huge upset?
Paulie fights at 140, and Khan has been wobbled by much lesser fighters than Paulie, so I wouldn't be so sure. I pick Paulie by UD12, but I would not be shocked if he gets a stoppage. I think Khan's chin is that much of an issue.
Malignaggi by KO. He'd stun Khan with a counter and throw proper punches to finish him off. Malignaggi in about 8.
Khan has not even cleaned his domestic plate. He is not even the best in the UK, which is not particularly strong at the moment. Malignaggi would stop him in the late rounds, he is a class above Khan at this stage.
