I'm going with B. They didn't make a trade and throw away top tiers of prospect just to make a trade.
Lockridge I'm fine with. He'll have at least an option next season. They gained a fast pinch runner if they want to use say for extra inning 2b start. Chourio's injury may have enticed the pick up.
Miller is a plus for the bullpen. Being on IL, I'd hope he will have a fresher arm for the stretch.
Think the progression on the team and however far they go in the playoffs, will gain experience to put a go for it next season vibe. I think this team's weakness as a whole, is matching up vs HR power teams. Yankees are a terrible matteam's.
The Cubs and Nationals series show how much the Brewers defense really is superior advantage.
