Yeah, I went over there on a rugby tour with my representative team a few years back, and wellington was pretty small so.
I think NZ should give up on the two fly halves tactic that seems to have caught on, Nonu is really a key in any game, and too good to not be using.
Also, with the new ruck law, meaning that even the tackler has to roll away before attacking the ball, McCaw won't be as effective at the breakdown.
