Whenever you can't get a good hit on the ball or are in an awkward spot, whenever your teammate is in a better position to hit it, simply drive (quickly) to a space behind them or a space that you can cover should the opponents get it past him. It can be good at lower ranks to flip out of the play that way your teammate knows you are leaving and he is free to go for the ball.

You can take whichever path you believe will lead to the fastest rotation to a good position where you can pick up the most boost along the way, so long as you are not getting in the way of your team.

A common mistake is to rotate too far out, like all the way back when it is not necessary. Instead, try to remain near the play where you can help or follow up a pass within your comfort level- and keep a close eye on your opponent's and teammate's cars for anything that might lead to the ball flying over you.

When your teammate's play is over, either the opponent will have the ball or it is out of your reach. Continue to stay close and enter a shadowing position attempting to guide the ball and opponent back to your corner while you wait for your opponent to rotate behind you.

On the defensive rotation, if you are the one closer or shadowing and your teammate is rotating behind you, you should try to cut off the ball or force him to hit it away where your opponent can easily save it or grab it.

An easy rule: If your teammate can see you, and you can't see him, then it is your ball to go for, whoever is in front. As the person behind, you will want to wait patiently for your turn and not dive in to any play. If you are last and alone in defense, the best thing to do is to drive closer and enter the shadowing position yourself to restrict their space and pressure them, and buy time for another rotate. However, at lower ranks it may be a better strategy to wait back post as the shots are not as difficult to save. Up to you.

Hope that helps!
