In MLB every bat, ball, player, and individual limb of every player is tracked dozens of times per second during every live play. I earnestly struggle to think of anything on the field a scout can provide that can't be seen on camera or recorded via tracking. Even soft stuff is generally pretty well known publicly by most fanbases at this point, not to mention player/coach movement. MLB/Advance scouting very much feels like a "you have to do it because it's the way it's always been done" deal rather than something that actually matters.
In the upper minors, we have pretty low rent broadcasts and a lesser version of Statcast. My understanding is teams have full statcast for the minors, but I'm not sure what the video situation is. Soft stuff, I'd imagine you know pretty well for other teams in your league, but not as much for other leagues at each level? I would probably want scouts in the Cal League, the PCL, etc. primarily to pick up on hot goss. I wonder if the seven guys remaining are one for each level for full season and one for each league at the complex level?
For amateurs you desperately need scouts. That soft stuff is absolutely essential, since work ethic adaptability, etc. are so key to future growth. Thankfully sounds like this area's not being touched.
All in all I mostly shrug at this? Like even the line about the Astros adding scouts misses the context that when they were in their successful run under prior leadership they were the original pioneers of this type of scouting structure and were wildly successful at it.
