There are plenty of projection systems that are released before the beginning of baseball season each year. One of the more notable ones was developed by Dan Szymborski of ESPN and Fangraphs called "ZiPS." The ZiPS system is a computer-based projection of performance that predicts a player's rate and advanced stats, though its way of measuring predicted playing time isn't exactly 100% accurate. Often times players are projected for far more major league at-bats than they figure to receive, and some players projected won't even make the majors at all in 2016.
The Milwaukee Brewers' ZiPS projections were released on Friday, and they actually didn't look half bad.
