This is pretty in the weeds, but basically Eno Sarris and team built a projection system using their Pitching+ metrics. Stuff+ is basically a measure of a pitcher's pitch qualities based on things like their velo, spin, etc., while Pitching+ also folds in location/command. It's interesting because it is completely independent of ball in play luck or anything like that, I believe the only results based metric that goes into it is swinging strike rate by pitch type. Because it focuses more on process than results, it stabilizes really quickly, often just a couple of starts. Overall, the results are pretty positive for the Cubs. Here's how guys' ERAs from this system compare to what's currently projected on Fangraphs Taillon: 3.91 PP / 4.20 FG Stroman: 3.71 PP / 3.80 FG Steele: 3.82 PP / 3.78 FG Wesneski: 4.02 PP / 4.56 FG Thompson: 4.15 PP / 4.15 FG Alzolay: 3.65 PP / 3.86 FG Smyly: 4.49 PP / 4.55 FG Hendricks: 5.01 PP / 4.61 FG Kilian: 4.26 PP / 4.15 FG That's nice lift for Taillon, a huge lift for Wesneski, and some other more modest gains elsewhere. Hendricks is pretty much the only pitcher who looks way worse by this methodology.
