Nearly all english are like that ( with some notable exceptions). I believe Khan got caught in the "gladiator" mentality usually on display with the lemons: look as well how Ricky fought against Money. Nuff said.
partly that he's only been fighting bums (apart from Limond and Gomez), but also because he doesn't know how to fight smart...it's all very frantic. He cannot tie his man up, cannot defend etc.
