Clip 2 – 4 March 2019 - Law 6
The Lions are playing the Bulls at Ellis Park in Johannesburg. The Lions' jerseys have red on top and white around the torso. The Bulls are all in sky blue.
The Lions are on the attack. Burly Carlü Sadie charges forward but the Bulls pull him, down. This leads to a contest for the ball. During the contest, the referee sees that the Bulls have knocked on. He signs and says "Knock-on Blue". He then adds: "Advantage Red, er White."
There are two ways of naming teams it seems - by colour and by name. Here it seems the referee initially forgot which colour he was going to use for the Lions.
Question: why use colours at all?
The teams know themselves by their names. In the case of these names, Lions is not longer or more difficult than Red or White, and Bulls is not harder to say than Blue. There seems no reason not to use their names, especially when teams are multi-coloured as they often are.
There was a match in the past between the Blues of Auckland and the Bulls of Pretoria. The Blues were in white, the Bulls in blue. The referee then called the Bulls 'Blue' and the Blues 'White' - which was a useless, unnecessary and confusing thing to do. Their names would have been easier and more efficient.
