About casimero I don't think if he get the 100% sure support by the crowd after these issues. And yes he still have a chance to fight and being a champion again.
He already got the support when he was still a champion, people accepted his style in boxing, he is trash-talker, so what? as long as he wins and make his countrymen proud, that's important, now it's time for him to correct his mistake and that is by bouncing back with a win, probably in a new division.
