England may not have 15 who could start a fight in an empty room, but we do have a 15 who could start a fight in an empty aircraft hanger! Is Hartley a particularly aggressive player? He does his fair share of getting nose to nose with the opposing front row, but that's pretty standard. I don't think that his demeanour around the pitch is particularly confrontational outside the odd well publicised instance of thuggery or stupidity.
