That's a fair criticism, I have little knowledge of the schematic changes since the early to mid 90's.
I'm curious what differences you've seen between the decades, and more importantly, I'd love to know why you think those styles of offense are no loner ran.
Good post! Repped!
Thats a good question - let me try to answer it, albeit in layman's terms.
The truism is that the old NBA was a run-n-gun league that played no defense. That is overly simplistic. There were many teams in the late 60s and 70s that played very good half-court defense - which is *why* teams ran when the chance was there. The best teams also knew how to quickly shift gears and run an efficient half-court attack. Attacking off the dribble was not the norm. The best teams attacked off the pass. (and that required constant motion by the guys without the ball)
Case in point: if you ask younger fans who the best PGs of all time were, many will name Oscar Robertson. Almost nobody names Jerry West or Walt Frazier - but in current terms, they played more of a "PG" role than Robertson did (until latein his career). The reason, is that Oscar had impressive APG numbers, and the other 2 look very pedestrian. That was because *everyone* on those Knicks and Laker teams was expected to move the ball, and hit the open man. The same was true of the Celtics, post Cousy. Heck, did you know that WILT had a couple seasons where he averages around 8 APG?
Why did it change?
1) Expansion. Everybody points to how it diluted the talent pool for players - but it did the same for coaches and refs. On top of that, the increased number of teams made in season scouting less feasible. Teams no longer game planned for a specific opponent, until the play-offs.
2) The league got younger. As players started leaving college sooner, the emphasis shifted from skill to physical talent. Gameplans became less sophisticated.
3) Marketing changed. "Lakers vs Celtics!" became "Bird vs Magic!" There had always been a "star" system, but it became the tail wagging the dog.
4) Officiating changed. Some teams (Daley's Pistons, Riley's Knicks, Jordan's Bulls) were suddenly playing with private rulebooks.
5) The 3 point shot. What used to be considered a bad shot from the perimeter suddenly became more valuable than working for a high percentage shot. Teams feel less pressure to work for a good shot, knowing they can always just throw the Hail-Mary....and get on Sportscenter as a reward.
I'm sure that barely scratches the surface of the subject, but take it FWIW.
