Great great match up. Barrera was a level above anyone that Inoue has fought and I can see him possibly dropping Inoue as well given that he has a great hook. Inoue hasn't seen anyone with the skills, aggression, and sometimes dirty tactics that Barrera had and would have to fight tooth and nail to win. Barrera was also very versatile as well, although I do think Barrera's best chance to beat Inoue is to outslug Inoue which comes with a lot of risk. 50/50 fight for me honestly but I wouldn't count out Inoue's chances to hurt Barrera bad and stopping him late.
Inoue's record IMO could be better but I think he gets a close points win over Barrera. Fantastic match-up.
