SCREENING Rule 4.39 &
Points To Remember Regarding the Screener:
The opponent being screened may be stationary or moving
Some screens are from the front or side of the opponent and the Screener can be SEEN by the opponent. This is a Visual SCREEN.
Some screens are from BEHIND and the SCREENER CANNOT be seen. This is a BLIND SCREEN
When Screening using a Visual Screen – the SCREENER may be as close to the opponent as he desires – short of contact
When screening an opponent using a Blind Screen – the SCREENER must allow the opponent one normal stride backward without contact
When screening a MOVING opponent, the SCREENER must allow opportunity to avoid contact. (Time/Distance – not more than two strides)

4. SCREENING Rule 4.39 &
When SCREENING an opponent moving in the same path and direction as the SCREENER is moving – the opponent is responsible for contact, if the SCREENER slows or stops
There is no such thing as a MOVING SCREEN FOUL – there MUST be CONTACT
The screener may NOT move to maintain the SCREEN. In other words – if the SCREENER is Moving – the SCREEN CANNOT be legal (with the one exception above)

5. SCREENING Rule 4.39 & 10.6.3 POINTS TO REMEMBER:
A player who is SCREENED within his VISUAL field is expected to avoid contact by going around the SCREENER
A player who receives a BLIND SCREEN may make inadvertent contact with the SCREENER, and if the opponent is running rapidly, the contact, may be SEVERE
Inadvertent contact is to be ruled as INCIDENTAL CONTACT if the opponent stops or attempts to stop on contact and moves around the screen
If the SCREENER has the ball and the inadvertent contact displaces the SCREENER – a foul would be called instead of traveling
A player may NOT use the arms, hands, hips or shoulders to force his way through a SCREEN or to hold the SCREENER and then push the SCREENER aside in order to maintain a guarding position on an opponent
