The closest approximation is probably the current iteration of the Spurs. I know, they have at least two and maybe three Hall of Famers on the team. But at 38 and 37, Duncan and Ginobili aren't stars by any measure. Parker is 32, and nifty as ever, but he's got 14 NBA seasons under his belt and he's lost a half step. Point being that the Spurs lack a go-to isolation scorer, but they overcome that weakness through spacing the floor and perfectly executing an offensive system that requires smart, precise passing.
Just a minor point about the Spurs...
It's true that the Spurs have the best basketball structure of the modern era (seemingly perfect skill development, roster management, rest, preparation, offensive and defensive system, etc.), but this often leads people to underrate the talent on the team, especially because Pop so deliberately limits minutes and distributes offensive and defensive responsibility. So on the one hand, this is an environment that allows players to thrive where they otherwise might not, but it also limits their statistical output, leading many to underrate the talent on the team.
C/PF:
Splitter: Statistically, he rates very well and is a top 5 or 10 C when playing. It's difficult to know how much of that is due to the system he's playing in, but he's clearly a talented and skilled big-man.
C/PF:
Duncan: Yeah, he's old and doesn't play much in the regular season. When he does play though, he's still elite for his position. Duncan had the third highest RPM (rate stat) of any PF or C last year, trailing only Dirk and...Nick Collison. BPM, like any encompassing NBA stat is highly imprecise, but just about all stats and subjective experiences would agree that Duncan is still very good when he plays. How many post players would you take over Duncan for a playoff run, right now? Davis, Howard, Love, Blake, and Dirk...maybe? Aldridge, Noah, or Bosh? Probably not...
SF:
Leonard: Just won Finals' MVP, arguably outplayed LeBron at times in the Finals, ESPN's RPM rates him as the 6th most effective SF in the game, and WS/48 ranks him 11...of all players. Already an elite defender and rebounder who can shoot. One can reasonably argue that he's a top-10 player right now. Who'd you take over him at SF? LeBron and Durant, obviously. Not sure about Melo or even a healthy Paul George.
SG:
Ginobili or
Green: Also old, but rated as the #2 SG in the league, according to RPM. 17th best overall player according to WS/48. He can still run an offense, pass, shoot, create off the dribble, etc. Green is one of the best 3 point shooters in the game and ranked as the 4th best SG in the league last year. What ball dominant SG would you take over Ginobili for a playoff run? Harden, sure, but is there anyone else? Is there a better off-the-ball SG than Green? Maybe Korver or Klay Thompson?
PG:
Parker: Statistically, he's actually a weak spot, ranking 13th among PGs by RPM, although WS/48 really likes him. Most scouting reports would agree that he's an elite offensive PG when playing. There are definitely a few PGs most would rather have for a playoff run (Paul, Westbrook, Curry), but outside of that, I'm not so sure.
Then on top of that, they have players like
Patty Mills,
Belinelli, and
Boris Diaw, who also rank well statistically and have a multitude of skills. Even their worst player,
Matt Bonner, is a big 6-10 with elite 3-point range.
So, yes, the Spurs have an arguably perfect system that makes it easy for their players to thrive, but they also basically never have a lineup that's not highly skilled at all 5 positions.
Another way to put it, how many players on the current Celtics roster would even make the Spurs team and how far down the depth chart would they be?
