Kat, it helped Wales that they were able to bring the likes of Jones, Charvis, and Thomas on ... if only we were so deep! That was the key, I think, for Wales as the starting group was well and truly rattled.
I think Canada gave as best as they could, but maybe need to work on being mentally strong for 80 mins. I imagine that's our biggest issue, given the structure is sound. Was the same vs. New Zealand, as I imagine some players couldn't believe they were doing so well up to that stage and just got a bit complacent. One biggie is that many of these boys will be around for 2011. I'm sure Ric has the people (and his own talents from what I hear from a friend who was with the women's program under him!) to build from this and make them even better as these youngsters get their feet wet on this, the biggest of stages.
... and we don't spin it because Wales would have murdered us more out there. Canada have some of the most intense forwards out there, and you have to play to your strengths. I do agree, however, that 10 pick and goes around the fringes in a row is a bit much. If we're going to play 10-man rugby, I'd like to see more variety - crashes off 9 and 10 rather than just pick and drive. What'd help is if we had a 'Gareth' who can provide the quality kicking game a forwards-dominated team needs.
As a coach who (I think) knows his stuff, I am immensely impressed with their defensive structure. They are shutting the ball down well as it comes out of the ruck/maul/set piece. The problem with this (even easier to see in teams who play Rush def.) is that when your defence plays at such a tempo, as the game progresses, and minds get tired along with the body, one person not doing his job perfectly opens massive holes for the attacking team. Was the same story v New Zealand.
Best of luck in the next round ... esp. to my adopted 'brothers' in Samoa and Argentina! 8)
