Cora is blameworthy, but I hesitate to base that on the lineup.
The telling truths are--
1. He has the same high-priced rotation he had last year but without Pom, who bombed. So far they are pretty awful.
2. He also has pretty much the same lineup less Kinsler, who didn't hit much, and plus Pedey, who still might be able to hit (and field). They are about half as good as last year.
3. He has most of the same bullpen less Kelly, who looks awful so far in LA, and Kimbrel, who can't help this bullpen because he only pitches the 9th, preferably with no one on and a 3 run lead. The bullpen is less and less effective, but I blame some of that on how much Cora has to use them when his starters can't go 5 innings, let alone 6 or 7.
4. He has the same defense minus gold glover Kinsler at 2B.
5. He also still has the highest payroll in MLB.
