Do you think Boxers sometimes talk to each other on the phone b4 a press conference?

I mean let's be honest, a lot of the prefight stuff seems fabricated and sometimes fake. I can imagine Zab Judah and Danny Garcia or Mayorga and Fernando Vargas talking to each other on the phone before a press conference and during that call they figure out what to say to hype the fight. You guys think that happens often? I can imagine it does happen. I do not have proof, but... at the end of the day both fighters know the more hype the fight gets the more money they make (PPV or in the future) It could sound like this: Zab: "Danny, Ima call ya dad a b*tch and call you a bum". Danny: "Cool"
