Ofc the main event is the most important factor when it comes to PPV buys. But a shitty undercard can still ruin the buyrates. Since this has a direct effect on the biggest part of the income of a champ I'm surprised noone has ever complained about the card he has to perform on. Examples: Johnson vs Horiguchi Aldo vs Mendes 2 Dillashaw vs Soto Also, does anybody know how the PPV split works when there are two Championship fights on one Card? If both champs get the same cut as they usually get the UFC would be losing out since buys don't double.
