Davis' PER will end up top 10 all time for rookie big men

Here's the top 20.

Everybody ahead of him is older by at least 2 or 3 years except for Shaq and Webber.

As he 's started to average 30+ mpg, his PER has continued to climb.

1. Wilt Chamberlain* - 28.0
2. Walt Bellamy* - 26.3
3. David Robinson* - 26.3
4. Bob Pettit* - 24.4
5. Ray Felix - 22.9
6. Shaquille ONeal - 22.9
7. Tim Duncan - 22.6
8. Kareem Abdul-Jabbar* - 22.5
9. Maurice Stokes* - 22.1
10. Alvan Adams - 21.7
11. Chris Webber - 21.7
12. Anthony Davis - 21.3
13. Hakeem Olajuwon* - 21.1
14. Bill Russell* - 20.9
15. Alonzo Mourning - 20.8
16. Yao Ming - 20.6
17. Ralph Sampson - 20.1
18. Bill Walton - 20.0
19. Zydrunas Ilgauskas - 19.7
20. Pau Gasol - 19.5

I rooted out the fluky numbers by using guys who averaged at least 25 mpg.
