I think a lot of this gets read into too much. Unlike Soares, Longo doesn't plan a press conference or statements. He answers questions that are asked, but does so crassly.
If you watch the video, he doesn't lead with that info. He doesn't guide the conversation into talking shit about Belfort. Helwani asked specifically about Vitor's past, and Longo gave a one sentence answer saying that he should play by the rules. Then they move on.
Everyone should watch the interview. Longo seems more interested in talking about how lucky he is to have his coaching job and how proud he is of his team. Even when talking about Weidman being injured, he was very careful to not that he's not taking anything away from Machida. Longo is crass but respectful.
