The 32-30 result at the Stade de France was a hammer blow to Wales, and it denied them the Grand Slam. The damage it has done to their hopes of winning the Six Nations title is not terminal though and I have broken out my tartan scarf for tonight's France Scotland game.
Because France won with a bonus point but Wales picked up a losing bonus point last week, Les Bleus now trail Wales by five championship points in the table with one game left.
Les Bleus must beat Scotland with a bonus point tonight. That will draw them level with Wales in the table and the title will be decided on points difference.
Currently, Wales have a points difference that is 20 better than France's. Therefore, France must win with a bonus point and by at least 21 points.
(If France beat Scotland by 20 points with a bonus point and both teams are tied on points difference, then the tournament will be decided by the number of tries scored. Currently, Wales have scored 20 tries and France have scored 15 tries. What happens if France beat Scotland by twenty points and score five tries I don't know.)
If Scotland win by eight points, they will finish second in the table above France which will be their best result in the Six Nations ever. I haven't double checked this but I heard Stuart Hogg say it so it must be correct.
