I look at it this way, if his velo is down compared to normal, I would call it a injury about to happen.
It's the same thing that happened to Josh Hader, when his ERA went from 1.23 to 7.31 in 2022.
We traded him and in and after a full off season of rest it went back down to 1.76 so it's a very real thing IMHO for the non-believers. Josh, this year in Houston, after 60 appearances in 138 games it is creeping back up there to 3.28
