Not all his major league moves have been head scratchers, but he's made 2-3 doozies. When you spend $1-10M on mostly 1 year deals, you get what you pay for, and I still am not so sure Bloom has done worse than most GM would have done with the contract sizes he was afforded.
To me, the bigger FA moves before 2022 (Wacha, Hill, Strahm) looked better than before 2021 (Richards, Perez II, Marwin,) but the W-L record did not reflect that. Of course, other moves were made (Renfroe for JBJ, the Barnes extension, and Diekman,) but there does not seem to be a clear correlation.
Ultimately, it ends up being the results on the field, and Bloom has clearly missed with his SP'er additions, even if most were bargain basement stabs in the dark. He chose to spend more in other areas, but even on this area, our SP'ing has been doing more than fine, lately, and we are doing worse.
Baseball is hard to figure out.
