The division is weak, so yah, it isn't impossible to compete next year. Maybe the Cubs try to spend a bunch and have the best team on paper by a mile...but that doesn't assure them anything. Not saying they can't, but banking on the postseason being a decent scenario...is a pretty generous and optimistic outlook. I don't think assuming that wouldn't happen is some kind of terrible opinion on my part. I think 75%+ of Brewers fans would say we have little to no shot.
I am optimistic we can have an offense that isn't completely embarrassing, but that rotation needs some serious TLC. Losing Woodruff, Burnes, and even Miley is quite crippling.
