The reason for the step back is to make a bigger target for the point to run his man into the wing - who will be setting a pick as he hands the ball off to the point. The wing hands off the ball and he rolls to the basket. Point passes to wing as in previous drills. Wing squares up to the basket. The point takes 2 hard steps to the basket and then makes a sharp cut toward the wing - he now comes over and sets a pick for the wing who has the ball.
Point passes to the wing.
The wing dribbles toward the lane - the point changes direction and comes off the wing for a hand off. The wing should do a two foot jump stop and be balanced as he hands off to the point man. You can put groups at each basket and you will be teaching alot of different fundamentals.
