2. For the sake of this argument, let's assume Retallick is the first receiver. What are his options? It would take too long to list them all, but here are a few.
He can take the hit up himself - there's nothing wrong with the direct approach. He's a big man and will draw in defenders.
He can throw a short ball to Sam Whitelock.
Retallick could throw an inside ball to his blindside wing. It is an effective way of utilising Julian Savea's strength and again holds those inside defenders. He can throw it out the back to initiate back play. If you think back to the try Beauden Barrett scored against South Africa, it was this sort of scenario, except the first receiver was Conrad Smith. Aaron Smith hit him with width from the breakdown, Barrett looped around and receieved a pass out the back and beat a player to score.
Really, there are abundant options.
3. So why have the All Blacks gone away from it?
I can't put my finger on it but I'm guessing they feel they have to constantly evolve to avoid becoming predictable. The game is relentlessly analysed now, so the coaches are constantly trying to develop their approach to attack and defence.
This might be a case of them saying, "We've done it, it's predictable, time to move on".
I hope not. It's too effective to be shelved.
