The game situation basketball drills are designed to practice a specific action that you will use in a game. It is not about working on conditioning, but to specifically work on one one type of game movement.
For this basketball drill you are going to work on feeding the post, and then relocating once your defender turns their back to you. This is an action that should happen every game, and you need to be prepared for it. Another great thing about this drill is that it will help reinforce good habits for the player even if they don't end up getting the shot, because a lot of times players will post feed, and then just stand and watch.
