I don't know a huge amount about women's rugby, but I'm led to believe that the USA match is the crucial one.
England are favourites along with New Zealand for the tournament and Kazakhstan are supposed to be tournament make weights. The US is stronger in the women's game than the mens.
Even that won't necessarily be enough to get us out of the group as it's the group winners plus the best second place team into the semis. If I was a betting man, I'd go with a semi line up of New Zealand, England, France and Canada.
Couple of fine canadian players on this thread half way down the page....they put the irish girls to shame
