If France are to win, then they must score a try or two. Not an easy asignment as Scotland found out.
For all the endeavour and enterprise that Scotland brought to the game, England countered it with disciplined defence and their backs have so much speed to chase down half breaks. All the criticism levelled at the English (attack) seems to overlook the fact that it is dam hard to score tries against them.
And so far England, when behind on the score board have been able to keep in touch with teams (Argentina, Scotland) even though they are well behind in general play. Had Argentina or Scotland been able to stretch the lead over England by 10 - 12 points or so, then maybe England might have succumbed to that 'score board' pressure.
No way can France win by penalty/drop goals so I hope France can put a couple of tries on the poms. That will obviously to the French the world of good. And it will put England into a very uncomfortable position whereby they have to actually 'play rugby' to get back into the game.
Please France, do not just capitulate if it is tight. Play with verve, desire and belief. Play to win.
