When the wings are running in, the backcourt players often disturb them.
In this example the attacking LB prevents this.
The ball starts with LW, who passes to LB.
LB moves quickly in and sets a screening on defending R2.
While doing this she passes the ball to CB.
LW runs in behind the screening LB.
CB puts a pressure to the right and passes the ball to the incoming LW.
CR sets a screening on R3.
