Mauro honestly makes Rogan look good and I used to like him back in the day…last time he wasn’t horrible as a commentator has to be Strikeforce days though…

💯💯💯 You realize this when you hop over from player development to pure projections…obviously the two fields are intertwined but if for example you want to build the best possible K% predictor at a league wide level you’re not using Stuff+ or just Stuff+…
A few random thoughts on Stuff+:View quoted post on X
Stuff+ is highly reliable, which makes it predictive in low-information environments (small samples, new arsenals, showcases).
That doesn’t make it universally predictive. Once you have real outcomes and stable peripherals, those explain future performance better than a static Stuff+ value.
Often, weighting each of them can help as you are in the middle ground between minimal information (all stuff+) and say strikeout-walk % stabilizing (projection model).
Accidentally stumbled on a @fangraphs bug on UI -> Yamamoto's link auto sends to his fielding page and you can't click on the classic pitcher dashboard. Appelman hit me up for that QA work baby I got you ;)
Long shot but does anyone know of a maintained database of MLB player/game combos that have exited a game due to injury?
