Most likely someone that's not PPv worthy..
If he ain't fighting GGG or Jacobs,, the only viable options in my opinion are Saunders or at the very least Eubanks jr... I think those are the most worthy contenders to the throne and the only ones PPv worthy, and Eubanks is a stretch
The idea of Rosado is appalling and possibly as sad as Mayweather/Berto or Pacquiao/Bradley... It's pathetic. Oscar needs to stop acting as bad as the horrible promoter who brought him up, it's horrible. Starting to lose all respect for this kid and De La Hoya.
I say Sam Soliman, non-threatening puncher who is old but has been in with a decent amount of big names.
Geale, Ndam and Lemieux would all work also but each is coming off a loss. I think they let the Lemieux fight simmer because that fight could be something decent for GBP if they let Lemieux reestablish something.
No one else has any cache, I guess they could go with Heiland or Soro being highly ranked but not costing much.
