FanGraphs released the 2017 Pittsburgh Pirates ZiPS projections by Dan Szymborski today, giving a look at how one of the best projection systems feels about the Pirates for the upcoming season. The numbers this year predict that the Pirates will have a good offensive group, with an above-average lineup that will produce about 21 WAR, which is above the ~15 WAR that a group of eight average players would produce. On the flip side, the pitching doesn't have as much depth, mostly in the bullpen.
The biggest thing that sticks out to me on the offensive side is the outfield alignment.
