This sidecourt out of bounds play takes advantage of a basic stack play, but under conditions where the defense is really denying the inbounds pass.
Players O4 and O5 line up in a stack free throw line high on the ball side. The defenders guarding O4 and O5 are denying as O4 steps out of the stack to the ball side. O1 quickly gets the ball to O4 on the sideline, and the defender guarding O5 should be taken out of position to cover O5, who rolls for the basket and takes a lob pass from O4 for a layup.
At the same time, O3 sets a backscreen for O2, who cuts for the basket on the far side of the court for a possible lob pass from O1 or O4.
If neither is open, O3 rolls to the ball and takes the inbounds pass from O1.
