No doubt, Bloom failed on his drafting of pitching, but the idea of drafting the best available player has a wide following among GMs. It's sad to say that maybe his best pitching choices was not trading Houck or Crawford and trading for Pivetta and Wink, along with the Rule 5 pick of Whitlock.
I will say, draft picks often take 3-6 years to make an impact, so the jury may still be out. His drafts rounds:
2020 (only 4 picks total): 4 Wu-Yelland, 5 Drohan
2021: 4 E R-C looks promising, 8 Dobbins & Guerrero, too.
2022: 3 Rogers, 5 Dean, 6 Hoppe, 10 I Coffey and 12 Mullins all look like long shots.
2023: 4 Duffy, 5 Early, 9 Wehunt and 14 Ingrassia look faw away.
IFAs: Paez & Nunez "21, Portes '22 (traded away by Brez) & Cohen, C Lee & A Bates in '23 and in 2024, D Reyes looks promising.
Overall, these were Bloom's major and decent+ additions to the Sox pitching system (farm + MLB)
Pivetta, Wink & Robles (trade)
Whitlock (Rule 5)
Kelly, Bernardino, Schreiber (MiLB FA/Waivers)
FA: Jansen, martin, Wacha, Hill, Strahm, Paxton was okay for $10M
This list is not impressive, at all.
