Reffing and the level of violence that SA rugby bring to the game are the stuff to look at.
SA rugby bring nothing rugbywise. They can bring a sense of excitement over violence though.
The expectation is that violence will not match the level displayed against FR, and even less one that could happen against PI teams as SA rugby players went on biting streaks against them.
EN players can not be bitten in large numbers, the EN union has too much weight for this to happen. It has so much weight that the level of violence wont match violence as shown against FR.
While violence is one of the added value of SA rugby, SA rugby players should keep quiet as they fear retaliation from the English who control the institutions and the laws.
Violence under the colour of the law is always easier to achieve. Without the cover of the law, it is hard to imagine SA rugby not staying quiet.
