While on paper this looks like it could be a semi-competitive fight I personally think its going to be one sided in Roman’s favour.
Daniel Roman is the bigger fighter who has been competing on par with the best fighters at Super Bantamweight and only just lost his world titles in a fight which could have gone either way. Payano on the other hand has been stopped by both of the top guys he’s faced recently and seems to be on the decline. He’s also moving up a weight class which can’t be good at this stage of his career.
I think Daniel Roman will win this fight by KO and move on to fight for a world title again shortly afterwards. I still think he’s one of the best 122 pounders in the world and is fully capable of regaining a world title.
