It's a simple enough equation for the All Blacks in their quest to retain the Bledisloe Cup this week - they have to extend 50 minutes of brilliance by half an hour.
Deliver for 80 minutes in Dunedin what they managed for 50 in Sydney and it will be all over for another year.
The Wallabies saw that first 50 minutes as a catastrophic failure of their defence - a capitulation of their basics. The All Blacks believed it was somewhere close to their best football in the last decade and as always, the truth lies somewhere in between although probably closer to the New Zealand version of events.
Some of the timing, execution and awareness in that period was exceptional. The speed the All Blacks moved the ball and moved themselves was at a higher level to what they produced in 2016.
There have been plenty of All Blacks teams that have felt they were loaded with pace, but this team are maybe different in that, with Rieko Ioane, Damian McKenzie, Ben Smith and Beauden Barrett, they have four deadly strike weapons. They have four men who can beat defenders one-on-one just by putting the throttle down and it was that element which destroyed Australia, and it will be pace which the All Blacks will again see as the key to victory this week.
