Whereas Gregorius has a .630 OPS everywhere, this year.
If Didi actually can walk out to shortstop I don't think it will be a focus. Joe wouldn't even consider benching him, for one thing. That said, can this team actually win anything with the current Didi and the current Bohm? They need both of them to come around and they need to Cutch to keep it up, or they need to add one serious bat to lhe line-up at least one of the three places.
And it's true, we lack prospects to trade but that comes back to the same old question. If they're not all-in, they may as well be out.
Rentals don't cost what they used to because everyone values prospects more these days. Problem is we can be outbid by teams on three different fronts - deeper system, greater chance to win, and willingness to spend $ (maybe).
