All you need to know about the UFC 220 prelims is that Kyle Bochniak and Brandon Davis are the headlining contest. Davis has never fought in the UFC while Bochniak sports a 1-2 UFC record… and that one UFC win was controversial. Mark my words here: if this PPV sells well, it will be very telling of the star power of Francis Ngannou as I don’t think there is another notable selling point. There sure as hell isn’t on the prelims.
Nonetheless, I would advise keeping an eye on the flyweight contest between Dustin Ortiz and Alexandre Pantoja.
