Southpaw that throws a good straight left and a right hook has a shot any day any fight. You just can't see a right hook when you have to watch for the already akward straight left.
Still way too early to tell...Let JuanMa's career play out first. He still has BIG fights ahead of him like JMM, Gamboa, Cabellors....If and when he goes through that gauntlet. We can truly determine whether or not he can in my opinion?
JML has yet to destroy an elite. He's destroyed decent fighters, but Deleon, Concepcion, etc are not Morales, Pacquiao, JMM, or Barrera in their featherweight days, but from the looks of it he would of given any of them hell. Until he beats Gamboa or John we'll get a better idea.
