Durant
MJ
Stockton

Hakeem

Lebron
Ray Allen
Magic

Russell, Curry

And, if I'm allowed a full active roster of 13, I add Rodman.

[Celtic Fan Forever]

PG: Magic/Curry
SG: Jordan/Kobe
SF:  Lebron/Bird
PF: Duncan/Durant
C: Kareem/Shaq

Oscar Robertson and Bill Russell as my last 2 guys.

I have positional and play style versatility and they can match up with any era.

[Birdman]

PG: Magic..Curry
SG: Jordan..Bryant
SF:  Bird..LeBron..Durant
PF:  Duncan..Malone..
C:    Kareem..Olajuwon..Joker

[Roy H.]

Why Kobe?

Why Kobe?

Why would you question Kobe being on someone's list? What am I missing?

[Roy H.]

Why Kobe?

Why would you question Kobe being on someone's list? What am I missing?

Because he's a selfish, inefficient chucker who clashed with teammates and coaches throughout his career?

[GreenEnvy]

Magic
Jordan
Bird
Duncan
Russell

Kareem
Hakeem
Shaq
LeBron
Robertson
Kobe
Stockton

[Moranis]

For starters I'm taking the best player at each position in league history, but for the bench I will focus more on role players that I could see being ok on the bench on this type of team

Starters - Magic, Jordan, James, Duncan, Kareem
Bench Smalls - Lever, Kerr
Bench Wings - B. Jones, Korver
Bench Bigs - Rodman, C. Robinson, Eaton

I think that 12 man has the right mix of scoring, defense, passing, etc.  The right amount of specialists on the bench.

C=Wilt/Jokic
PF=KD/KG
SF=Bird/LeBron
SG=MJ/Klay
PG=Curry/Lillard

Kawhi, Dirk


Starters run through MJ and Wilt with shooter's on the ready to snipe. Bench is a blend of talent that covers every aspect of the game.

[gouki88]

Curry - Jordan - LeBron - Bird - Kareem

Magic - McGrady - Durant - Garnett - Russell

Duncan & Kidd to round out the bench, both of whom can fill in multiple positions if the team went small or big.

Since I've been following the NBA closely since around 2013 I will take my team from the last decade.
A nicely rounded roster of 15 guys. To choose between Durant and Antetokounmpo for my starting PF is impossible. For fit I say Antetokounmpo with Jokic upfront and Durant with Davis on the second unit. In parentheses number of MVP awards.

PG: Stephen Curry (2) / Chris Paul / Damian Lillard
SG: James Harden (1) / Luka Doncic / Russell Westbrook (1)
SF: LeBron James (1) / Kawhi Leonard / Paul George
PF: Giannis Antetokounmpo (2) / Kevin Durant (1) / Jimmy Butler
C: Nikola Jokic (2) / Anthony Davis / Joel Embiid

I don't know if you could get away with Harden and Curry defending PnR's with Jokic. Would move Kawhi to the 2 spot personally, as the passing from Jokic & LeBron will cover everything.

My second unit would get weird with Paul, Doncic and Harden together. Obviously I didn't make a big tactical approach. But I agree in practice Leonard in that starting line-up would be a better fit.
