Haven't watched Karl-Anthony Towns play? He didn't need a year or college nor do several of these kids. They are the minority, but there are plentyI haven't seen Moses Malone or Darrell Dawkins recently but if a kid thinks he can go to the NBA straight out of HS go on then bro.
We discuss this every season (it seems), let the kids go league if they so desire, if they fail go home to Mom & Dad or overseas.
If you commit to a school how about sticking around to learn the game.
