Well I guess you haven't looked at most posts... like mine:
Jump Shot: Steve Nash (already the best shooter ever, FG + 3PT + FT cumulative) / Ray Allen / Kobe Bryant
Jump Range: Lebron James / Chuck Person
Outside Def.: Gary Payton / Bruce Bowen
Handling: Pete Maravich / Rafer Alston
Driving: Lebron James / Dominique Wilkins / Allen Iverson
Passing: Magic / Nash / Stockton / Maravich / Bogues (best assist to turnover ratio ever)
Inside Shot: Shaq (almost 60% career avg)
Inside Def.: Ben Wallace / David Robinson / Tim Duncan / Hakeem Olajuwon / Many more
Rebounding: Wilt Chamberlain (Seasons of over 27 rpg)
Shot Blocking: Mark Eaton (3.50 bpg career avg)
Stamina: Wilt Chamberlain (47.2 mpg career avg)
Free Throw: Jose Calderon (2008-2009, 98.1%) / Steve Nash / Rick Barry / Mark Price
Experience: Oscar Schmidt (One of the best never to play in the NBA) / Robert Parish / Michael Jordan
This is an excellent list, one of the best I've seen. Any disagreement is mere quibbling. I wouldn't put Bruce Bowen on the list, and I find it odd that no one ever lists Scottie Pippen. Dennis Rodman belongs on any list for both rebounding and inside defense. That is not the same as saying he's better than Chamberlain. I would put Bogues on the Handling list.
Not sure why everyone is in love with Jose Calderon. He had that big streak, but I don't feel like he's even in the top 5 or 10 all time. This past year he shot 79% from the line. You're right on with Price Nash and Barry, but then you should have Reggie Miller and Larry Bird. Those guys all shot 88% or better for their _career_.
Still, one of the best lists on this thread. Kudos.
