Amongst everything else already discussed, this is also a relatively speaking "low BBIQ" team.
The past few seasonsn every analyst noted how the ball movement was crisp, the passes were on point- hitting the recipient in stride, the off ball movement was constant.....
This season the ball is sticky. Much more dribbling, and it's often side to side or with back to the offense. Players wide open on cuts go unrewarded. Players off the ball are standing still or stutter stepping trying to figure out their place on the floor.
