It's a given that any of the TV networks will cheer on the team playing us. You hear it in little things like "He was brilliant! Fooled the Dogs defence completely to score that try"; and "That was poor defence; they let the Dogs player step around them to score an easy try". The talk is generally around what the opposition needs to do to beat us when they're behind, to superlatives of the opposition if they're in front. If it had been the Broncos beating the Tigers, all we would have heard was how great the Broncos were. Instead, we had sympathy for the Tigers, and cries of foul when refs missed something in the play.
It ain't gonna change.
