It's a long time before this kid has to make a decision. I think it is a little early to assume he is going to jump straight to the NBA. We forget that high school kids were allowed to make that jump previously and while any of the top ten HS kids in any given class may have declared for the draft, all of the top 10 kids NEVER did so in the same year. The most ever was nine in 2005, also the last year before the one-and-done rule. I have no idea if all nine were rated as top 10 kids or not, but it seems safe to assume that most of them were. But there were also years like 2002 when only one player went that route.
Obviously we live in a different world now, and with the NBA focusing more on development these days perhaps having all of the top 10 kids leaving early WILL become the norm. I'm just saying that I'll be interested to see how it plays out, and what the top kids tend to do when the rule changes goes into affect.
It is definitely a game changer, but I'm not certain about HOW it will change the game just yet.
