Six Nations: The weekend review

Ugo, Ashy and a very happy John Barclay review round two of the Six Nations after Scotland regained the Calcutta Cup. Is a first triple crown since 2010 now on the cards? Did Scotland's gameplan expose England's weaknesses? Should it have been Marcus Smith on the bench at Murrayfield? And is his namesake Fin getting enough Test minutes? France flex their muscles in Cardiff as they put 50 on Wales, can anyone stop the defending champions from winning another title? But why are Wales still struggling defensively under Steve Tandy? Ireland's fly-half debate rumbles on, will it be Sam Prendergast or Jack Crowley lining up at Twickenham? And what is the biggest obstacle preventing Italy from being in the title hunt one day?
