I honestly don't think this moves the needle one way or the other very much at all.
We need a front of rotation arm, but we also needed a depth arm. They just got the depth arm first which really is to be expected since the depth arms are easiest to get.
Does it kinda suck that they had to give up a controllable reliever that could very easily have been a back end type piece next year and the next 3 after that? I guess, but they are relievers growing on trees every year in FA and your own farm from other failed starters that can probably fill that hole, so it's not really something to lose sleep over.
