Yes, just like Manny, he do the talking in the ring and used his fist to shut the big mouths of their opponent. I think Lopez will later regret spewing all this insults.
That would not happen, there's no regret, Lopez is not a fool and he knows he is an underdog in this fight, can lose against Loma but if he can sell the fight better, he will get a good share of the revenue, that's what boxers do now, they fight for money, big money so I don't really believe a lot on what they say as for all we know it's just a marketing technique.
The split is already predetermined, Lopez is already guaranteed $ 1.x million, and there are no PPV here, that's why he was offered that big amount. Initially he has rejected it and Loma step up and agree to have his pay cut just to be able to salvage the fight. Of course, boxing now is business, trash talk and stuff, but most of the time, the fighters that is so loud mouth losses the fight, except perhaps for elite boxers such as Floyd Mayweather who can walk the walk and talk the talk.
