Do you have a 4 that can attack the basket or shoot it? This might work well for your team. Shooters (2 and 3) space to corners as threats and to spread the defence. Your 4 starts at the weakside low block or short corner. Trail big (5) is opposite the ball outside of three. 5 starts the action off the top by sprinting a weak to strong side lane cut to the ballside corner. The new position of 5 spaces 2 to be a wing threat. 4 times their flash cut up to the weakside elbow and looks to play (Princeton chin action) after receiving pass from 1. For 1, the first option is to sprint a brush cut under the ball to the strong side corner (which spaces 3 to a wing threat).
Second option for 1 is to set a little on big ballscreen for 4 to use and read up top. Regardless, 4 is looking to attack the rim, kick out to a shooter, or shoot. After screening, 1 reads the defence and spaces appropriately (flare, lane roll to rim, etc). As with any action off the top, timing and spacing are important.
Check back regularly for plays that will be posted. This one will be helpful if you are trying to isolate a player at the top of the key. 1 dribbles at 4 which pushes 4 to sprint the lane line then space to the ballside corner. 5 sets an angle screen for 3 to use coming off the wing. 3 makes an "Iverson" cut off the screen while receiving the pass from 1. Both 4 and 2 are available for kick passes and corner shots, while 5 spaces (flare, roll, etc) to be visible after setting the screen.
