I posted this late last night/this morning but thought I would repost it here. I will follow up with the top players at other positions according to wins as well.

This ranking takes 4 of the basic measures for wins that are readily available. From ESPN I used EWA (which is based upon PER) and WAR (which is based upon RPM), and from basketball-reference I used Wins Shares (based upon their advanced stats) and WORP (based upon their +/- ratings). I averaged those 4 ratings together and here is what I got:

1. Stephen Curry (19.8 wins)
2. Chris Paul (18.6 wins)
3. Russell Westbrook (16.6 wins)
4. Damian Lillard (12.6 wins)
5. Kyrie Irving (11.3 wins)
6. John Wall (10.7 wins)
7. Eric Bledsoe (9.2 wins)
8. Kyle Lowry (8.9 wins)
9. Jeff Teague (7.6 wins)
10. Ty Lawson (7.1 wins)

Parker and Rondo do not merit inclusion on a top 10 list this year based upon how they've performed this season. In past seasons they would very much deserve to be on this list, but not this year. Extending the list through the next 10 here's how the next group of PGs would rank:

11. Mike Conley (7.0 wins)
12. Goran Dragic (6.2 wins)
13. George Hill (5.8 wins)
14. Isaiah Thomas (5.7 wins)
15. Reggie Jackson (5.3 wins)
16. Kemba Walker (4.9 wins)
17. Deron Williams (4.3 wins)
18. Darren Collison (4.2 wins)
19. Jrue Holiday (4.1 wins)
20. Elfrid Payton (3.8 wins)
