Yeah I don't think they should do moves like this but if they really do want to win the WS they will need to swing for the fences in FA and hit some home runs. Signing Snell and getting 5 WAR out of him next year before he implodes, trying to get a 30 homer season out of O'Neill before his roid-addled muscles tear off the bone, going over the luxury tax on 1 year deals for expensive and old pitchers, etc. are the types of things that I think they could consider.
You are kind of argumentative toward me in your post (granted, you'd probably argue with me if I said the sky was blue so it could just be your posting style) but I don't recommend these moves, to be clear, so I think we are mostly on the same page.
