Predicting Angels' 2016 starting lineup

FanGraphs projects the Angels to be mediocre this season, at 81-81, four wins shy of last year's win total. Take that with a grain of salt. Those same projections, produced by Steamer, had the reigning World Series-champion Royals finishing the 2015 season with that same .500 record.
It isn't Steamer's fault, of course. Too many variables and too much unexplainable luck factors into a season. These projections, no matter how diligent, will always be an inexact science because the future will always be so unpredictable. We nonetheless tried some of that below, by projecting the Angels' Opening Day lineup, rotation and bullpen.
• Comeback candidates | Newcomers | Prospects | Deep rotation
It's a difficult task this time of year, especially this year, with Albert Pujols (right foot) questionable for Opening Day and so many roster spots open for competition. We assumed Pujols at full health to provide a glimpse at how the lineup should look for the majority of the season, and we accounted for as much of the Angels' starting-pitching depth as possible.
