Well kids get more coverage than ever before from high school
Essentially.
Most teams have cut back on scouts, on the ground, a hell of a lot. Most, to my understanding, gather in all of the available game footage and watch that and selectively scout from there.
Along with the fact that a lot of this is known about the kids from high school, there's years of tape, stats, and interviews.
They obviously do some IRL scouting still. It's just more targeted and focused than it used to be. Most justified it by saying any savings on domestic scouting they'd put into putting international scouts on retainer.
