Per the Herald, he's OK with the situation. Guess there's a big difference between demanding and requesting a trade, and how adamant you are.
From Barry Jackson's article: "The Marlins felt more urgency to trade Christian Yelich than J.T. Realmuto, who also has asked for a trade, because they believed Yelich could become a sour presence in the clubhouse if he wasn’t traded, according to someone with direct knowledge of the team’s thinking.
The Marlins believe Realmuto will be a good soldier if he isn’t traded (and) feel no obligation to trade (him). (They] would only do it for an overwhelming haul in return. The Washington Nationals reportedly want Realmuto but are unwilling to give up either of their top two prospects."
That screams Marlins spinning Realmuto's story to show they have more leverage in a deal. Still, Realmuto can't force a trade, and because he is in arb, his performance will dictate what he makes, so he can't just sit out.
Still, the Marlins know he is most valuable now, so if the offer is good enough, they should take it.
