I don't see a reason not to trust them initially. I never liked the Belisle signing and they probably should have aimed higher than Breslow, though I was intrigued by his changes enough to approve the minor league signing. While they were uninspiring in major league signings, I give them much more of a pass on how the depth had shaken out. So much of the current situation is based on what they inherited. It is so difficult to add impact depth from outside the org, unless they blew up the major league roster. Levine and Falvey, fwiw, have both commented multiple times on how much of the second tier plan for relievers had been ravaged by injuries and required the scramble. This is pretty clearly true and does seem like they had something of a plan going in. All that to say, while I am critical of the major league additions to the bullpen, I don't think that should necessarily mean they don't know how to evaluate their own internal options compared to scrap heap veterans they continue to add.
