I don't think easy. Commentary I have heard (Craig Hutchinson who knows a bit about sports media rights) is that the AFL had the perfect conditions for their deal. Strong competition, etc. The market now has less competition, and with Fox apparently up for sale, this has further depressed the market.
What the big deals have is content. 24+ weeks, lots of teams, national footprints (at least for AFL and cricket), uncertainty of outcome, huge local followings. There is big competition for these which means there is less for other sports. RA are essentially selling around seven tests that are in prime time, another five or so that are in the middle of the night, and super rugby which gets terrible ratings. They don't have the world cup rights to bundle so that actually reduces the amount of product they have over four years. We've also been pretty dire for a long time which has seen people switch off.
The main hope is getting another platform interested enough to push the price up, but the outcome could be worse in terms of visibility than what we have now. There is also the restriction that most of the prime-time games need to be on free to air, which means even a streaming partner would need to do a deal with one of the tv networks.
