Set-up is so the PG attacks the mid-line, allowing the Ghost BS to flare to the corner.
Ghost BS needs to be a shooter
Clear out and lift opposite once the PG changes direction towards the middle.
PG DHO to 2, who catches going downhill and is making x3 decide whether he will stop ball or stay tight on shooter
X4 can be open if his man exaggerates help
If x1 switches or sags on DHO, 2 can drive, reverse pivot, and kick out to PG who should be shaping up behind his penetration.
