The division winning Cardinals are undoubtedly worse. The moneybags of the division Cubs are undoubtedly worse. The Pirates are still awful, and poorly run, so I don't see that improving drastically soon. The Reds have improved significantly, but have disappointed in previous seasons after "improvements". Brewers have probably stayed the same, some areas better (depth, starters), some worse (offensive production, team defense). So, enough to be a contender? For the division? 100% they have. Any further than that depends on a lot going our way, but I can see high 80s for wins without too much optimism.
