Perena try was pretty obviously a try, and I don't really see how someone could argue agaisnt that.
On the other hand Aaron smith holding on to the Welsh player to prevent him scoring in the first half should have been a penalty try IMO.
Completely agree with people saying Crotty is not up to the usual AB standard, saying he's reliable is using the same logic that kept Brad Barrit in the English side and Zane Kirchner in the SA side, I don't think it's unreasonable to expect something extra from an international especially an AB. Same goes for Sam Kane and Savea, no idea what's going on there other than the selectors being too stubborn to admit they were wrong.
As for the game itself it's really classic All Blacks, every time you think you have a chance they score three tries in the last 15 minutes
. Can't see them losing a test to the Welsh or even coming as close as they did today. ABs are just to good.
