do you run Read & React? we simply play half-court 4v4 with no dribbles. i usually give the offense 5 possessions to score (1 shot + rebound putback), then we switch offense to defense. Whoever scores more wins. We validate the win with a FT. loser has a quick consequence.
if you don’t run RnR, then you can do the same thing with your offense. Just play a scrimmage with NO DRIBBLES. you can even do it full-court to work on your press break.
if you don’t move off the ball, there isn’t going to be much offense!
just my two cents.
