Let's look at the pitching DD brought in: Price - best name available, but record of suckage in the playoffs. Not DD's fault that his 2017 unfolded the way it did.
Sale - great acquistion, record of fading, but debatable if Farrell rode him too hard or what.
Pom - has turned out well, never should be in a position of starting him game 2 of playoffs though.
I think we're missing a dependable #3 innings eater. I am not wholly blaming DD for the pitching, but there's really no depth to it.
