LOL.. if Caleb was thinking that he'll get the public on his side with all the trash talk, then from the previous experience I have to say that he's wrong. Earlier he had some support from the fans, naturally because he's the underdog. But many of them would be repelled by the provocations from his side. That said, I don't know whether I should directly blame Caleb. Perhaps there is a chance that the organizers asked him to do that, in order to get some cheap publicity for the fight (I won't be surprised if that is true).
Yes, it's really a bad move by Caleb to make his way to the fight and trash talk Canelo. He will pay dearly for it, Canelo doesn't talk but maybe deep inside he will surely aiming for the head and knock out Caleb if it presents itself. Caleb on the other hard is making himself into a deep position because how can you trash talk a fighter wherein he is destroying everyone in the path? And Caleb will not gather any support from the public, on the contrary he could be hated for this for the rest of his boxing career.
