The NL East is much-improved. The Phillies obviously improved their lineup, although their pitching is still very questionable. The Braves are counting heavily on a slew of talented but young and unproven starting pitchers. I actually think they could revert back to 4th. The Mets lineup is improved with Alonso, Cano, and McNeil added to the mix, and if they keep DeGrom, Thor, and Wheeler healthy...with a strong backend to the bullpen...they are a real threat.
The Marlins even have a nice stable of 4 young starting pitchers that look very promising. They have a terrible lineup, but they aren't going to be easy to pile runs on.
