It's not easy to get team to trade in May, but it can be done, if desperate enough. Bloom did let it go too long, but I will say that Dalbec had a .595 OPS on June 8th of 2021, and was still at .648 on August 5th. Bloom/Cora were praised for sticking with him. as Dalbec was essential to our offense after August 5th. That was about 100 games into the season, too.
I'm not trying to paint this season's 1B as some sort of success story: clearly it was not. I'm just saying the winter/spring plan was sound. We had a career .813 1Bman returning and a seemingly decent back-up in Shaw, as well as out top prospect, who was ML ready of very near so waiting in the wings. Dalbec and Shaw sucked, and Casas got hurt in the end of May. Waiting 100 games did not work, this year, like it did last year, and our 1B play was a big reason we were on the outside looking in at the deadline.
That being said, I don't fault Bloom for the initial plan for 1B. I don't fault him and Cora for giving Dalbec and Shaw a look-see. When Casas got hurt, one can make a good argument a trade should have been made, at that time. It's hard to expect a GM to get a deal done in one day, so let's say June 1st. That was game 51. I'm fine with saying Bloom dropped the ball from game 51 to 105 (deadline). Personally, I thought sticking with Dalbec, after seeing what he did in 2021 made some sense, beyong June 1st, but there is a lot of merit to say no to that idea.
Trying Cordero was a disaster, but was trying Schwarber the disaster many predicted, last season? This doesn't absolve Bloom/Cora. I'm not trying to argue the moves were justified or successful, but I do think some context is needed to judge the severity of the choices that were made. Hindsight is always 20-20, and who is to say, had we made a trade June 1st, maybe the guy we got would have sucked and we happen to have benched Dalbec right before he was going to get red hot- like last August and September? Of course, we know now, he did not, but at the time, no GM could know the future.
It was a mistake, in hindsight. At the times of the choices, one can argue most made sense or some sense.
