It looks like top 25 players are staying in the league a lot longer. 2012 has a combine 14 players from both sites still in college. 2013 has 13. It looks like the one and done rule is finally doing what it was meant to do. Keep the kids who aren't ready for the nba to stay in college until they are ready and the nba to draft players who are closer to being ready.
The rule is good for the NBA, I don't think that was ever in doubt. But is this any different than it was before? Looking at the top 25 from 2009, I see the following.
1. Avery Bradley (one and done)
2. Derrick Favors (one and done)
3. Xavier Henry (one and done)
4. Demarcus Cousins (one and done)
5. John Wall (one and done)
6. John Henson (stayed three years)
7. Renardo Sidney (stayed three years)
8. Jordan Hamilton (stayed two years)
9. Kenny Boynton (stayed 4 years)
10. Mason Plumlee (stayed 4 years)
11. Tiny gallon (1 and done, but wanted to return to school couldn't because of ineligibility)
12. Lance Stephenson (1 and done)
13. Daniel Orton (1 and done)
14. Abdul Gaddy (stayed 4 years)
15. Wally Judge (stayed 5 years)
