Other than Fighting Harada, of course! Mainly at Bantamweight, but I don't mind Featherweight mentions either.
I don't know if I can see anyone being able to convincingly beat Jofre @ BW, other than Harada who was an ATG fighter. Stylistically the worse would probably be Jeff Fenech, who is pretty similar to Harada, and maybe Ruben Olivares. Still, I would not favor Fenech or Olivares over Jofre. FW is a different story. I would definitely pick guys like Pep, Salvador Sanchez, and Alexis Arguello to beat Jofre.
Azumah Nelson at 126. A green Nelson on a two week notice gave Salvador Sanchez his most difficult fight of his career.
Terry McGovern has a shot against anyone at 118, even someone as iron chinned as Jofre. Wilfredo Gomez at 122 is suspect. There are quite a few featherweights id favor, most have been mentioned. A high pressure swarmer is the worst matchup Jofre, so at 126 Henry Armstrong would be absolutely awful for him.
