Pretty standard stuff really. Why is it so many boxers sound like they've got a cold? Froch does there, Hatton often does, and so does Haye too. Perhaps from being punched on the nose so much I guess... It's more of a sniffle though...
Pernell Whitaker and Johnny Tapia always did, not that I'm suggesting Froch has been copying any of their between-fight "recreational" habits
