If he will not get traded this trade deadline, I'm pretty sure he will opt out on his final year of his contract and will be a free agent, or maybe the Heat will go to a sign-and-trade deal in the off-season. Whatever the case is, he will be traded either this regular season, or next season.
But those are just rumors, did Butler really ask for a trade? If he did, then you might be right. However, if he’s not giving 100% like before, it could be because he’s no longer inspired or invested in the team.
There is no request as far as I know, and he try to quash the rumor. However, sources are legit that's why there is a noise about it. And even Pat Riley has step up and says that it's not true. But it's hard to dismissed as we have seen that the Heat is struggling this season so it's really concerning, so maybe he is considering a trade.
When a player doesn’t like where they are, they often just go through the motions, contributing the bare minimum while ensuring they avoid injury to maintain their trade value. If that’s the case, it could explain his recent performances.
That's what I'm trying to say, we've seen his performance although he rises to the occasion during playoff and last year they had a incredible run although he got injured. So there's a lot of if on Jimmy right now if he still wants to be a Heat for the rest of his career or chase other teams like the Warriors, with Kuminga in talks for a trade.
