Henson is rugby's Anelka. Brilliantly talented players who will never quite fulfill it because they are so far up their own arses they define the term 'arsehole'.
You don't storm off the field if you don't get your own way; and if your captain asks you to do something you f***ing well do it.
Having said that, if you're winning narrowly in the 6N then you kick the ball out and end the game. No one remembers anything other than individual results and who won the Grand Slam. Whoever tops the table is, frankly, irrelevant; the big prize is the Grand Slam because the 6N has always been about bragging rights amongst heavy rivals, and no one can have bragging rights if they've lost a game.
