I would say the trinagle is more about organizing pieces and setting a structure than "ball movement". The triangle can get pretty stagnant with a lot of looking and standing around for role players. A system like the Princeton offense is more about "ball movement".
The drving on the tringle offense came from the isolations that this system created, or are you now going to tell me that guys like Jordan and Pippen didn't drive to the basket?
I do agree that there isn't much room for typical plays like a pick and roll, but then again, many times Phil Jackson teams would go away from the triangle offense and just run some basic pick and rolls. I'm sure many Lakers fans here can attest to that.
And then again, how many teams had PG's that attacked the basket and ran pick and rolls time and time again? You won't confuse most PG's of that era (like Avery Johnson, Eric Show, Charlie Ward, Chris Child, Derek Fisher, etc) with driving threats, tbh. Were they not PG's because they didn't have these features?
