All of this being bad for High School players was predictable and many of us predicted it. A lot happened that hurts them right now. NIL, which I'm sure they covet, keeps players in the system longer. Less churn creates less openings anywhere in the system. That should work itself out over time, but it surely hurts a few high school classes. Then, on top of that, the NCAA decided to give four full years (ex. Ivy, so far) of players an extra year of eligibility. That is still not over, as guys like Posh and Wusu could come back. Everyone didn't use that, but combined with an increased pay structure, many did. It's a lot of extra players who would be off to other endeavors.
All 351 schools only need so many guys and players who have graduated from high school who would have had D1 offers in the past had to have been left out the last few years. It's math. An equilibrium of the total annual talent pool needed should arrive in one more year, but all but the truly top high school players can expect their best offers to be from mid or low majors. And from there, if they aspire to be high-major players they will need to prove it on the court. Young people mature a lot physically from 18-24, and there are exceptions like Stephon Castle, but not many 18-year-olds can play better than older guys.
Just ask Cal!
