Pop won his first NBA championship without Parker, Manu or Leonard. They were a very different team than the Jazz ever were. Unless you're saying Stockton = Parker = Avery Johnson, and Greg Foster = David Robinson. They did it by having two hall of fame bigs who averaged double doubles because they slowed the clock and pounded the ball into the paint. They did it with 3 guys in double figures, but Robinson and Duncan carrying the load, Avery Johnson being the third leading scorer.
With the big three, they actually went through years where their pace and overall scoring was down even further, the big three carrying the brunt of the offense. Methodical, slow play was still their thing, but with Manu and Parker at least having the ability for fast breaks.
That's the Spurs people think of, and probably haven't really watched the Spurs in years because they were boring. The Spurs of the last few years are very different than comparisons to Stockton averaging 11 assist, most on pick and roll Malone mid range jumpers. Watch the Spurs now they're pushing the ball and passing to spread the court to get everyone involved, not ploding along in a half-court offense.
To say the Spurs have had the same style of play for 15 years isn't very accurate.
And really, Stockton and Parker are similar play styles? Malone and Duncan? Pretty sure Duncan would have shot his way out of the league if he tried to rely on his mid range jumper the way Malone did the second half of his career. That Stockton, though, apparently known for attacking the hoop!
