As 3 reverses the ball back, the defense will have shifted over. The 4 and 5 man seal the defenders on the side and the wing man should have a wide open 15 foot shot.
2 or 3 should not stay out on the 3 point line unless we need three pointer. They should read the defense and see where they should be in the seam for the shot.
1 can misdirect this play a little be dribbling over and in and faking pass to the high post while they are sealing the defense.
