Personally I want to see the Salido rematch purely for the revenge factor ASAP.
Other than Salido, I think if we look at the 126, 130, 135, weight classes the best options are:
1. Winner of: Frampton - Santa Cruz Jr (Rematch)
2. Winner of: Zlaticanin - Mikey Garcia
3. Winner of: Corrales - Uchiyama (Rematch)
4. Jorge Linares
5. Francisco Vargas
6. Terry Flanagan
7. Jose Pedraza
Personally I think that if Frampton and Garcia win, they are the two boxers who have the biggest chance of challenging Loma.
