And that's part of the problem that does fall on Dombrowski.
Porcello is clearly having a horrible season, effort notwithstanding. But he is still out there starting games. Eovaldi is having a horrible season due to injury. He has had his role bounced around, but he is now back in the rotation. DD did got out and get Cashner, who was actually a smart pickup despite his failures at the time. But with all the struggles and injuries in this rotation, why so little effort to improve? Why did DD do nothing else? I get his trade assets were limited, for which he is culpable, but understandably so. But nothing else? Other teams in the playoff race have been at least trying. AS I pointed out on another thread, the Yankees have a killer bullpen, but they keep adding to it. Meanwhile Dombrowski looks at the Sox pitching and says "do better! That's it."
It's not his fault Sale and Porcello and Cashner and Eovaldi have struggled. But it is his fault for having no one else to pick up the slack...
