Constant bullpen overusage (leading to more injuries) and nonstop spot starts from OKC with pitchers who clearly are not major league ready just not a good approach at all from a roster building perspective.
When you look at the rotation who can you actually rely on for 150(!) innings. Snell Glasnow Ohtani May Gonsolin Roki all have extreme injury histories. Yamamoto is basically it and even he missed a lot of time last year and needs to be nursed through extra rest.
The way that the Dodgers approach pitching is broken. Constantly targeting injury prone stuff+ pitchers and then being surprised the rotation falls apart is just dumb. You can work around 1/2 guys in the rotation like that with depth but it's the whole rotation right now.
