What, if any, is the correct call?
Some people believe that if you are not in possession or contesting a ball you cannot be contacted legally. However, it would appear that the NAH ruleset has a clause designed to permit contact with someone who has executed a legal screen but is neither in possession nor pursit of the ball:
§220.127.116.11 – If a ‘screen’ is set that is stationary or momentary a bike interference penalty is not assessed, however legal bodily contact as described in §7.3.3 is allowed.
I believe that without this written exception we introduce a defacto “right of way” to the person executing the legal screen.
