a lot of this looks like the clips from the pacers/knicks game from the other thread as well, particularly with the overhelping, unnecessary crowding of the paint, and the lack of rotations BEFORE the pass is made. if players are only going to start rotating/reacting after a pass is made, they're screwed. ball is faster than the player.
this guy also pointed out schematic issues as far as switches. im skeptical that they'd actually want collins to be switching onto guards, and having somebody like vassell switch onto bam... but he's right that wemby/keldon/vassell/sochan, etc should be switching everything unless its just a piss poor screen that the primary defender can beat
to be fair, collins was basically a PF who played alongside poeltl. his mobility as a big is supposed to be one of his positive attributes, so push comes to shove, he should switch if its not too early in the shot clock
