You guys do know Ivan Robinson outboxed Arturo, right? What the hell do you think Khan would do to him?
It amazes me to see how many people actually thought Gatti was an A class boxer. He's a tough exciting boxer but he wasn't very good. His most memorable fights were with Mickey Ward! That should tell you enough right there. I might even pick Malinaggi to UD Gatti.
Much as I loved Gatti, he got completely crushed by anyone he fought who was even near being an A level fighter. Ivan Robinson's speed was too much for him, even though Robinson liked to stand and trade too much, and Angel Manfreddy (whose big accomplishment in his career was winning the WBU belt and getting beat down every time he tried to win a real title) solidly outboxed Gatti. Khan would kill him with his speed. The ref or the corner stops the bout somewhere around 8 rounds max to save Gatti.
Khan by late Tko most likely, or comfortable UD. IF Gatti some how won, it would only be by come from behind ko.
Khan would absolutely school him. Gatti has a punchers chance but doubt it. Khan by shutout UD or late stoppage
