You seriously believe Cora didn't recognize the problems with Kluber, Pivetta, and Kike? I like your posts a lot, but, if you believe that, you aren't nearly as smart as I thought you were.
Kluber got his shot as any acquired starter would, especially one with his background--especially when he's being paid $10M. As for Pivetta, as recently as last year he had the 3d best WAR among Sox pitchers and the 2d best among Sox starters. He started 33 games and had 12 quality starts. You appear to think he was dog doodoo. This year, agreed, he got hammered as a starter, but in the last month has learned how to be an effective reliever. The point is, when Pivetta started this year, Cora didn't have a whole lot of choices.
Finally, Kike. Another $10M player having a bad year. Two years ago as the Sox centerfielder his WAR was 4.9. This year he was moved to SS because Story and Chang are on the IL. That didn't work, but he also is 4th on the Sox in rbi's with 29. His WAR is a pretty bad -0.4, but it's still better than Schwarber's -0.6. Nevertheless the Talksox experts (like you) have branded him the world's biggest loser.
This year the Sox total salaries are ranked 15th in MLB. I know that's the lowest ranking in the John Henry era and suspect it's the lowest ranking in 40 years. And you act as though Cora's job is so easy, despite the dearth of front line starters and the injuries to Story, Duvall (who still isn't the Duvall of the first 8 games), Houck, Sale, Schreiber, Chang, et al--to say nothing of Devers WAR sinking to roughly what it was in 2017, the year before official rookie year.
