The 2018 ZIPS projections for the Arizona Diamondbacks came out last week, and shoewizard beat me to the punch with a nice write-up on them and their Steamer siblings. Rather than re-hash that, I figured it might be interesting to take a look back at the 2017 ZIPS number for the D-backs, and how those stack up against actual performance. As shoe noted, “good projection systems can get hitters “right” about 70-75% of the time and pitching projections barely over 50%. For me the interesting part is the Macro look. This guy may end up over, and that guy may end up under, but at the end the TEAM should be close.
