OP was about biased or incompetent coverage in the national media - and as much/most of it comes from Vic how it is usually told not from a national perspective but from a Vic perspective. Can't really expect 'local' media to report equally on all 18 teams. Unfortunate I know and particularly frustrating for those supporters of non-WA teams in WA, non-SA supporters in SA etc etc. But OP was about it being a national comp but with the national broadcasts mostly being parochial Vic broadcasts.
Langdon and Hardie seem to know about all the eastern state teams as well as here in the west.
