A close fight isn't a robbery. Mayweather vs Castillo was close. Fights like Froch vs Dirrell, and Shumenov vs Campillo II, weren't close, thus they are called robberies.
Oscar was never a MW, but sturm actually got US coverage by fighting him and then proceeded to return to Germany - so you can't be surprised that sturm got what he asked for - no fights against one of the top MW's in the world. to say sturm deserved something that he never pursued simply because he won 'a belt' just isn't true
Castillo - Mayweather 1 was reallly bad. Martinez v Cintron was god awful. Sergio Ko'd hime TWICE and then got screwed on the decision. Three birds with one stone! DLH v Mosley 2 was pretty terrible. Pac v Bradley cost the sport some fans as being fake, rigged and no better than pro wrestling. Even worse because Pac's popularity brought in mainstream fans. Kov v Ward was laughable but at least you knew it was coming.
Oh yeah I even made a few threads and a petition about that one. Good shout. https://www.boxingforum24.com/threads/poll-casa-santa-cruz.28064/ https://www.boxingforum24.com/threads/casamayor-santa-cruz-post-your-cards.28555/
