A bit harsh, but the two guys you mention play -- or were supposed to play -- two of the most important positions on the diamond: starting pitcher and shortstop.
Bloom deserves the ire of fans and media because he has built extremely flawed big league rosters that have, for the most part, failed miserably in the standings. He has spent plenty of money on busts, and hasn't spent enough to secure some of his "priorities" -- which is what he called Bogaerts.
No, the Sox shouldn't have paid X what he got from SD, and yes, we all agree Boston -- where Bogie wanted to spend the rest of his career -- could've signed him for a fraction of that a year or two ago when Bloom chose instead to ink a strikeout king with a bad throwing arm. And I could care less what Bogaerts' WAR is this year, because anything is better than what we got instead from Story, who hasn't even got out of boot camp yet.
Bloom assembled the worst pitching staff in Red Sox history in '20, refused to pay for better relievers at the deadline in '21 (like Houston did, which was the true difference in going to the World Series), CBOed another cellar dweller last year, and is now in charge of a bad defensive club that starts openers every other day. Sure he finally addressed the back-end of the bullpen -- hey, he did his job! -- but come on, Jansen also has five losses (one less than the staff leaders).
