The Pop-Duncan Spurs are an anomaly in the history of the league. The league has either had teams that were very good for a long time but never quite made it (Jazz...), teams that perfectly exploited a short window in time (The 94/95 Rockets come to mind, the bad boys) or teams that were dominant for closeish to a decade and won several titles (the 80s Lakers and Celtics, the 90s Bulls, the Shaq/Kobe Lakers).
But the Pop-Duncan combo of a team consistently fighting for a title for 17 years running winning titles 15 years apart, never doing a back to back, alternating wins / setbacks / Heartbreaks (That Fisher shot, that Ray Allen shot) etc for so long is just something that one cannot fathom.
I mean the 60s Celtics or the 90's Bulls are more "normal", more predictable, than what the Spurs have done.
They can be used as an example of many things done right, sure, but they are not a template because what they have done in unduplicable.
