There's no point hauling players off after 60 minutes if the ones who comeon don't actually contribute much. You might as well just keep the tired legs out there and I felt that was pretty much the case with the front row that came on at Eden Park.
If Wyatt Crockett, Dane Coles and Owen Franks were able to handle the Wallabies' scrum early in the game-at a time when Australia were more likely to have some energy and be able to compete-how come Ben Franks, Keven Mealamu and Charlie Faumuina didn't get much out of the Australian second-stringers?
Not only that, but I also thought the starting front row all delivered beyond their core roles.
They made some nice short passes, cleaned out rucks and did their tackling-all the added extras whichmake a difference. Not only did the new unit not deliver much in the set-piece, but they also didn't add much around the field.
With the next four tests against Argentina and South Africa, the set-piece becomes evenmore important.
NewZealand need to be super clinical at both scrum and line out time against those sides, and we can't drop off for 20 minutes.
We can't let changing personnel later in the game rob us of accuracy and momentum. Beauden Barrett has long set the example of what is expected froma bench player and did so in Auckland again.
Malakai Fekitoa tried hard and got involved but the man who I really want to mention is Steven Luatua.
He was dropped earlier this year and earned a reprieve only due to injury to others, but he has responded really well.
He's improved his work rate, been hungry and accurate and I thought he contributed at Eden Park last Saturday.
Other forwards who come on in future games need to do the same.
They need to up the energy and dynamism and make sure they walk off having given the selectors reason to think aboutmaking changes for the next test.
