I'm really digging XFO. The winner of Petkovic vs Correa would be a good next step up for Blaydes too.
Fun fact, Blaydes actually fought and defeated Daniel James in round one by arm triangle choke in the amateurs, however the fight isn't listed anywhere.
Blaydes seems to be the best HW prospect out of Illinois. The ranking would probably go something like:
Curtis Blaydes
Daniel James
Erick Correa
Wes Anderson
XFO seems to be high on James though, they're promoting him as one of the top guys on this card.
