Barrera beat Naz by counter punching, Naz wa better at counter punching than landing leads due to his bad balance, I don`t think Fenech could capitlise on Naz`s misses as well as Brrea did because he wasn`t a good counter puncher like Barrera and didn`t have his handspeed, Naz couldn`t get past Barrera high guard,Fenech used a high guard too but his gloves weren`t as active in that guard, Barrera kept Naz guessing by moving his gloves from his chin to higher and the would lower his gloves changing the target are on his face, I think Naz v Fenech would be like McCullouch v Naz.
Barrera knew to move to his left away from Hamed`s power punch, the straight left, Fenech never showed that kind of savvy.
126 Fenech had real hand issues; thus I think the Prince has a huge advantage. If I am using the time machine for this; It would be a much more fun fight at 122, where arguably both were in their pomp.
Jeff was a bull and one of the greatest head to head forces ever I think he savages Naz! different breed them two.
I think that was his best weight class. Too bad his hands had gone by then, as physically it was the best weight for him and he had more seasoning by then.
