I think the Rockies might pull something off this year, at least they might place 2nd in the West. Their offence is damn good, especially at Coors, mix that in with a good bullpen and all they need is maybe a breakout or two in their rotation (plus a healthy Brett Anderson) and they'll be good.
I also think the Marlins will actually outperform their odds at the least. Decent lineup and I think that Yelich will have a great full year, and their rotations is sexy (Fernandez, Hendo, Turner, Eovaldi)
