Agree that Ch9 favours the teams who are perceived to represent the largest audiences, namely Sounths, Parra, St George and Bullies. Also agree with Weapon head's point that if we win regularly and become dominant that will force Ch 9 to do our games. Case in point in 2003, we got lots of Sunday games on the expectation that we'd be travelling well after a relatively successful season in 2002.
They dont take into account that league fans in general will watch games they percieve to be interesting/exciting no matter which team is playing.
I dont think the commentators would have much say in selecting games, I reckon that would be the marketing people who are devising the strategies for winning the ratings. The commentators are just there to put on their show.
