Post Game-Carlton v Collingwood

[LP]

Collingwood used to have predominantly white backs on their jumpers and there was no sponsors on the back. Sponsors logos stand out better on dark backgrounds, hence the introduction of the black backs. I think also, Collingwood wanted to make sure that Port Adelaide was never going to be able to wear their traditional jumper which had a black back.
Also play was far less congested and there were a lot of one on one contests in the olden days. Nowadays, when you're at the ground, it is really difficult to pick up the players sometimes, particularly from a distance, on dull days or in fading light.

Sorry Jofo, there is no way known a genuine fan is going to be confused, they could all be wearing tutti frutti coveralls and we'd be able to tell them apart!

Even with eyes closed and ears covered, a Carlton fan can detect a filth supporter entering the room from the smell! ;D

The filth players are even easier to detect, they are the ones that instantly annoy you when your gaze falls upon them! Like when you swat a wasp before you have even recognised what it is!
