A reminder that other than the post, all other players are interchangeable. Numbers are used here to track players' movements.
In "low", when 1 passes to 3, he cuts through to the opposite corner. If the ball can be passed quickly into 5, 5 may look to pass to 1 as he cuts to the basket. 2 moves to the midline.
If 3 passes into the post, he has three options.
1) screen at the elbow for 2,
2) he may move to the ball side corner, or
3) he may cut to the basket.
In this option, 3 elects to screen at the elbow for 2. 5 looks to score first, then he looks at 2 coming off of the screen.
5 must read the defense on the catch. If he receives the ball and the defense is behind him, 5 dribbles to the midline, where he can attack the basket or pass out if help doubles down from the perimeter.
If 5 doesn't have a move to the basket, he can pass to 2 coming off of the screen or to 3 who has popped up after his screen.
If he passes to 2, 2 looks to shoot. If 5 passes up to 3, 5 moves up to the elbow, and "high" is run. Of course if 3 is a shooter and is open, he may shoot after receiving 5's pass.
If 3 chooses to cut to the corner, 2 sees this and sets a pin screen on 4's man. 4 comes to the top.
If 5 passes to 4, 5 moves to the ball side elbow to begin "high".
If 4 passes to 5 at the elbow, 2 would cut to 1's corner, 1 would move up, and "high" away, under, or over would be run (explanation later).
If 3 chooses to cut through, 5 first looks to pass to him on the give-and-go. 2 sees that he is not getting a screen from 3, so he again sets a pin screen for 4.
In this case, rather than come to the top, 4 curls hard around the screen, looking to get a handoff from 5. If 4 gets the handoff, he goes hard to the basket using 5 as a screen. If 5 hands off, he seals and drop-steps to the lane.
If 3 is unable to enter the ball into 5 and passes it up to 2, 5 moves up and begins "high".
If 3 cannot get the ball into 5 and 2 is being denied, 3 dribbles at 2.
Whenever a player is being denied and a teammate dribbles toward him, the denied player cuts hard backdoor.
In this case, if 2 is denied, he cuts to the basket on 3's dribble.
If 2 doesn't get the backdoor pass from 3, he cuts through to the ball side corner.
4 and 1 have moved up on 3's dribble.
If 3 passes to 4, 3 makes a diagonal cut to the basket looking for a return pass. If 3 doesn't get a return pass, he cuts to the opposite corner.
On 3's pass, 5 moves to the elbow and 2 moves up. "High" begins with a pass to 5.
3 has dribbled up and 2 has cut backdoor. 3 looks to pass to 4. However, if 4 is denied, 3 dribbles at him and 4 cuts backdoor. If 3 can't pass to 4, 3 passes to 1. 4 has posted up and 5 moves to set a flare screen for 3. This is now a top flare situation which will be discussed in more detail shortly.
When 3 dribbles across the midline, a backdoor/fill or flare situation is created. Before we continue with the offense, it is important to discuss the backdoor/fill or flare concept. The top flare concept will also be shown.
