I think Morales would beat him more often than not but Pac would always give Barrera a lot of trouble IMO. Barrera of the first fight (unless you buy all the excuses) was physically fresh and a smarter fighter than the young Barrera and Pac beat him down. And I was a pretty big Barrera fan but he didn't seem all that interested in a rematch for a pretty long time. I don't put too much stock in the second fight, Barrera was just extremely defensive, I don't see him fighting like that in his prime, he would fight smart but not like that.
