Maybe he's looking for more money if the fight is to be somewhere else. It could be good leverage. He has a point: he signed up to fight in New York. He didn't sign up to fight elswhere. Part of the reason behind the fight being in New York is that the crowd will be largely Puerto Rican and pro-Cotto. Were this fight to change locations that will likely change. Maybe he wants the crowd on his side in the later rounds. Nothing wrong with that really.
