I'll keep saying this...
Nobody forces a GM to draft a freshman that "isn't ready".
If some GM drafts Myles Turner over Frank Kaminsky in May...who's "hurting the NBA"...the kid or the NBA GM himself?
So you're covering for GMs and front offices who make poor decisions? What about the kids who spend 3 years in school and get drafted and still are busts? That hurts the talent pool. These GMs are tracking these kids from the time that they're 14. We don't need an extra year to see that the kids are busts. That's faulty logic.
