Greyling HAD to be sent off on Saturday night, rather than receiving a yellow card. His attack on McCaw was nothing short of a premeditated assault, committed in the open. If needs be, rugby must have the ability to use a video replay to get a decision like that right.
You would struggle to see a more violent act in the modern game and it was an ugly reminder of when Richard Loe was at his menacing worst.
As for the test itself, what a bore. Bring back Sonny Bill Williams, because he has the attacking skills to make the game interesting. There are so many test matches these days that the standard of entertainment needs to be higher. Dunedin's indoor stadium provided the players with the perfect platform, and they blew it.
The Rugby Championship as a whole is leaving a bit to be desired. It was probably no coincidence that the one and only vital offload in Saturday night's game, from Sam Whitelock, was delivered by a tall player. A major factor in SBW's ability to unlock the watertight modern defences was his height.
The All Blacks were saved by two factors - the truly amazing Richie McCaw and the Springboks' woeful goalkicking.
Some New Zealanders might fling the dirt at South Africa's limited game plan, but it was good enough for them to be the better side.
The game was partially saved by three outstanding tries, but beyond that we had to endure a lot of messy, stop-start trench warfare. Had the Springbok goalkickers been on target, all that turgid grunt might have at least made a bit of sense.
Foran claim laughable
Kiwi half Kieran Foran had to be pulling our leg when he claimed not to have got a touch on the ball for Manly's controversial try against the Cowboys. The only others who didn't think Foran knocked the ball forward were the video officials.
It is inevitable that those officials, Paul Simpkins and Steve Clark, will be demoted after such a blunder but the mystery remains - just what did they see that the rest of us didn't?
Without turning this into a witch-hunt, I'd love the officials to appear on TV, with the relevant video clip, and explain how exactly they came to their decision to allow the Manly try.
