I feel kinda bad for Wonderboy. He had 10 rounds with Woodley and won 6 of them. Shoulda been champ in the rematch, but it was such a quick rematch with no action that no one gave a shit when it was over and no one wanted to see him in the title scene soon after that. So he put the work into fighting backwards, beat Masvidal, dropped another controversial decision to an overweight Till, then ate a freak knockout from Pettis. So even though he'd be an interesting stylistic threat to Usman, a guy whose contenders seem to be a constant scramble, no one's clamoring for him to be near the top and he knows he's gotta win fights against people like Luque and Neal, and he's not getting any younger.
As for the Eastern European market? Eh, maybe. What are the biggest stars for them right now?
