I think Brez has done a very good job trying to fix the issues he inherited, but the Bregman signing did muddle things up for Cora, who had different ideas than Brez. It squeezed Yoshida, once Devers went to DH, so in that sense, it didn't ease the roster construction issue, at all, but building up rotation depth was a good idea, as we have already started our 10th or 11th SP'er on the winter depth chart.
I still think the pen construction was rather weak, and once again, we left our 1B depth thin by trading away Meidroth and Gasper, while seemingly being a bit overloaded in the OF and middle infield, if you count Anthony and Mayer as 2025 pieces.
It's not easy getting everything just right, and most teams will start the season with a few positions that are weak and or have weak looking depth.
If by "3rd option" you mean trading for a 1Bman, I'm not sure what is out there in mid May- maybe not much. Only 1 AL team is more than 5 games out of the WC. (4 NL teams are 7+ games back.)
