Pick and roll is a legal basketball move... by: Joe Waters - webmaster
If I'm understanding your question...the move you've described is perfectly legal.
Once you set a screen on a teammates defender, you have a few options - roll, pop out, etc...
However, the main objective is to block (screen) that defender to free up your teammate and give your team an advantage.
The key to setting a screen without being called for a foul is to make sure you are set and not moving when the defender is cutting toward you. If you move to block their path, then a moving screen will be called.
