Same, except I view a Levine departure as merely probable. You're exactly right about not knowing how they divide the work. If Falvey overruled Levine on something and insisted on negotiating with the Dodgers for Margot, for example, ditto the Polanco trade, then Falvey needs to fire himself. If they have separation of duties and Falvey merely said, "you're the GM, execute those trades if you believe in them," then it's time for him to put aside loyalty and the fact they joined the organization as a tandem.
The delay may be due to letting Thad try and negotiate a landing spot in some other organization first, again as an act of loyaty - a deeper relationship exists than with Popkins for example. I trust that they won't let that drag on too long.
