I tend to view a grand slam as being a different thing to the championship. Odd I know.
Having said that the best team over the course of the competition did probably win it. I think that Ireland won the game against England, rather than England lost it. Anyhow, it's the world cup next and this...
I disagree with the majority view of the french try. He only needed downward pressure, i.e. contact on the ball on its downwards trajectory. He did, just, and the ball made contact just before his foot landed outside the line. Definite try - there can be no argument.
