I don't cherry-pick data to deceive people in order to make myself look correct, that's a tactic that's manipulative and bad faith, the truth is more important than my or anyone else's egos.
I didn't check how he performed in any other starts with the velo so no I didn't cherry-pick based on velo. The reason I chose San Diego, Seattle, and Atlanta to compare is because they're in warmer climates, as you said maybe the velo was impacted by April Chicago weather (which yes I agree could definitely happen). All other early 2024 starts are in cold climates.
I just checked his 2nd 2025 start in Arizona at the end of March (again, not a cold climate). He was up about 1 mph from the San Diego start a couple weeks later, but still down a tick from the Atlanta/San Diego warm climate starts the year prior. Early-season warm weather starts in 2024 having among the best velo starts of his career as you mentioned make sense because 1. he was the youngest at this point, 2. wasn't pitching in cold weather, 3. early-in-his-MLB-career adrenaline could also have been a factor.
Also, I didn't say "I don't think the injury impacted his velocity", I said i'm not convinced it did. Meaning it's possible it had an impact , it's a causation/correlation unknown like Hottovy said. Hottovy also thinks it likely did, so ok that's good. But my point is that it was also down before the injury compared to a year earlier, so age is probably a factor there. It could be age+injury? Looking again, the article said his velo dipped in June to Aug after he came back then went up Sept-Oct so then maybe it did impact the velo. But Hottovy also said they were doing things to improve the velo post-injury that may have impacted his mechanics, so who the heck knows.
Anyways, not trying to be an arse, i'm glad they're aware and working on all these things to get him back to where he was before.
