France (15 points) Three games played, three bonus-point victories banked and the title at their mercy. If they claim another four-try win at Murrayfield on Saturday week, they will secure the crown with a round to spare, setting up a rousing grand slam opportunity in Paris. Above all else, though, Les Bleus have illuminated this year’s championship with their pace and attacking grace, not least “King” Louis Bielle-Biarrey who has been spectacularly good. How many other sides in the world, aside from South Africa, can also interchange their second-row and midfield pairings without missing a beat? Or casually whistle up gifted youngsters such as Fabien Brau-Boirie, Émilien Gailleton and Gaël Dréan who all look instantly to the manner born. When you factor in the squad’s collective ability with and without the ball – to date France have scored the most tries, 18, and conceded the fewest, five – the future looks dazzlingly bright.
