Piss off your biggest (only) client so someone else can pay you the same rate to film 13 Phoenix games. Bold strategy.
That is one reason why the FFA should consider an Auckland side. It'd make the rights here worth so much more, and something like what you suggest may become a bit more viable because it will nearly double the number of games here. The more viable the alternative becomes, the more sky will have to pay to stop the alternative from happening.
