The Matchroom/Queensbury grubs would have all the fights on PPV so no difference. It is the high frequency and low quality of 90% of PPV fights that are killing boxing.
With the purses mentioned they have to pay these to entice the belt holders to put it on the line, but it is difficult to sell cards on PPV in most countries when the undercards are weaker or do not contain fighters all from the same country. They would almost be better off waiting for DAZN to become established in more markets and relaunch with a worldwide tv dela on one platform. They would need 400k worldwide $10 subscriptions to make the model work. Only way i can see it working as TV is a tough sell unless you are truly getting household names, golovkin, canelo etc
