blow it up for this year. Yes, they're barely out of first place. But it's clear their offense is not going to contend for anything this year.
Don't trade away future pieces at the deadline to get a band-aid that probably won't help the anemic offense anyway. Fire Servais. Get a new group in there and actually build for next year.
That being said, I haven't looked up how much of the pitching is under contract for next year or the year after (pretty sure Castillo is through next year). It has just been so frustrating to watch them the last month. And if they manage to squeak into a wild card game they will be out quickly.
