Players definitively better:
1. Durant
2. James
3. Wade
4. Bryant
5. Howard
6. Rose
7. Chris Paul
8. Griffin
10. Dirk
Potential Betters:
Possibly Pierce
Possibly Deron Williams
Possibly Carmelo
Possibly Kevin Love
Rondo is top 15.
Griffin, Dirk, Melo, and Howard do not make their teem-mates better. The players I did not just list, do, but most do not to the extent that Rondo does. Rondo can take over a game by scoring, passing, and to a lesser extent, playing defense. Chris Paul and Durant can not do all those things. Therefore, Rondo is in the same class as Lebron, Wade, Kobe, and Derrick Rose. I do think Kevin Love is arguably a top 5 player as well though. You cant argue with the numbers he puts up and the leadership he exhibits.
