Another flurry of red cards in the latest round of Super Rugby Pacific. 

Crusaders captain Scott Barrett has been suspended for four weeks after his shoulder contacted the jaw of Alex Hodgman during last Friday's loss to the Blues. 

Hurricanes hooker Asafo Aumua and Highlanders lock Josh Dickson have also copped suspensions after being carded during Saturday's game. 

So, why have teams still not been able to adapt to the new rules?
