From scouting fwiw, there is very little chance Moncada stays at 2B (there is a reason more 2B look like Pedroia than like Dez Bryant).
Breathe - the team is playing .500ish ball ... just like the Cubs and the Guardians. They're 0.5 games out of a playoff spot. It has been a weird season so far - since the team has not actually been able to string anything together - good or bad.
You are right about the Pomeranz deal and the Kimbrel one to a point. Sale - the price hurts some, but he is a really great pitcher. So far, DD's tenure includes a playoff berth, and a team with good chances of adding more. Now that is not all him - but no reason to panic yet.
