The ploy of having Kefu pick the ball up from No.8 should be a shock move played maybe only once or twice in a game. At present it seems to be the stock method of getting the ball away from the scrumbase due to Gregan's inability in that area.
I totally agree. I think I've pointed this out a couple times over the June internationals.
Except, I'm not sure its the halfbacks inability as much as the number 8's abiilty to protect the halfback, especially when the scrum is under pressure.
Definately a part of the game the NH teams seem to have an advantage in technique.
