The chin isn't the topmost attribute you want to be an ace prizefighter...unless you don't have a good one, in which case it looms larger on the list of neccesary traits.
Amir Khan has blazing handspeed and can put together an XL combo with flashy quickness and precision, but he also has a built-in betrayer, an iffy chin. Danny Garcia on July 14 tested the Khan chin, and three times, the Brit failed the test. He hit the deck three times and the fight was stopped in round four in Las Vegas. Garcia, who subbed in for PED-ensnared Lamont Peterson, snagged Khan's WBA junior welter title. We wondered after, and continue to wonder, if Khan will make like Wladimir Klitschko, and refashion himself into a defensive wizard or if at 25 years of age, his best years were behind him.
