Their forward crunch was spasmodic and the necessary French backline elan was missing against Ireland when the teams squared off with the loser to meet the All Blacks.
Ireland shed a heap of injured troops but France lost the skirmish and return to the Cardiff sporting cathedral on Sunday for the sudden-death confrontation against the All Blacks.
This will be the teams' seventh RWC meeting with the score at 4-2 in the All Blacks favour. Last time in Cardiff though and all that....
Dusautoir played that night when France stunned their rivals and the world with their 20-18 victory. The French flanker was an injury replacement for the tournament but his form was spectacular and he scored a try and made 38 tackles-more than the entire NZ side-in that contentious quarterfinal result.
Four years later he scored a try as he led his team to an extraordinary single point defeat after the All Blacks trounced them 37-17 in pool play.
That time, just like this, the All Blacks are the team to beat and playing at a level above France. Four years ago France resisted for as long as they could and as the score stayed close, their confidence grew to a level where they believed they could win.
"During the match we played well but we would have liked to have scored a drop goal on top of the great defence we produced. But we played an uncomplicated game and that is ultimately how we managed to surprise them so much," Dusautoir said.
The modest graduate chemical engineer forgot to mention his massive impact and galvanising leadership. On Sunday he and McCaw, a year older and with 65 more caps, will duke it out again for their teams' right to move on or pack their luggage.
