Glass Half Full
Acuña is an absolute stud, Freddie's last two months were an anomaly, Donaldson is healthy, Ozzie can be more consistent, having Mac back and Markakis provides veteran leadership, Dansby and Inciarte are elite defenders, Camargo coming off the bench makes the bench better, there is a ton of talent in the starting pitching staff, Another year in the system will make Gausman betterm Darren O'Day will provide a steady arm for the bullpen, the players love Snitker and would run through a wall for him.
Glass Half Empty
The improvement of young players isn't always a linear upward trajectory, Freddie can be injury prone, Donaldson is 33 and hasn't been healthy in a couple of years, McCann and Markakis could be washed up, Inciarte and Swanson are way too inconsistent offensively, they have no starting pitcher they can trust, they don't have a closer they can trust, Snitker is one of the worst in-game managers in baseball.
To me they're within a couple of games either way of .500. If things go right they're certainly contenders, but the fact that they didn't upgrade the pitching staff combined with Folty's injury concerns and the fact that everyone in the division but Miami got better leads me to believe they're going to take a step back but then again I thought they were going to be awful last year.
