I (obviously!) want Scotland to win!
I think last year if Scotland had won the Calcutta Cup, the positions of the two teams may well have been reversed.
Personally I can’t see past France.
An aside: Italy got some good results and ran some teams very close last year, could they potentially win the tournament at some point in the next few years. Or, to use an F1 analogy, will they forever be Webber/Barrichello/Coulthard/Massa?
