Aus and NZ used to blood their 10s at 12.Yes very odd. The ABs would never do this and Pivac is from NZ. Surround a new boy with experienced players is the way to start someone.
Lynagh's first tour was outside Ella.
Didnt Wilkinson play 12 for a few games?
Even if you have a close squad, making 10 changes always results in a disjointed game.
The same for Hardy. A new scrumhalf needs an old head at 8.
Only give the 9 clean ball. Or an old head at 10 who will take anything thrown at him.
8, 9 and 10 all raw with a 12 finding his way.
An all that with a pack unlikely to provide clean ball.
