I wanted to say that Paul George wasn't top 10 but then I looked at the best players in the league and just wasn't impressed.
Curry
Lebron
Durant
Westbrook
Harden
Davis
Cousins
George
Paul?
Lillard? 
I was under the impression that the league was getting better and more competitive, but is that really the case?
You forgot Leonard, Chris Paul, Griffin. I think Wall and Draymond Green are right there too. I don't have Lillard higher than any of those guys at least.
I do think the league is very deep but it is lacking in a few top level players I would suppose. Comparing it to different eras, especially the late 80's and early 90's. Even with the league being deeper now, if you go back to like 04-05' and look at all the greats playing at once even if the league wasn't as talented throughout, that's an impressive group. From the All-NBA teams that year:
Shaq, Duncan, Nowitzki, Nash, Iverson, Ama're, KG, LeBron, Ray Allen, Wade, Ben Wallace, Shawn Marion, McGrady, Kobe, Gilbert Arenas. Of course Pierce, who was left off there. Also Yao Ming, Melo, Vince Carter, Billups, Hamilton, Sheed.
A more impressive group of players to me.
