This is my “old man” moving screen play I run in basketball to create a lane to the basket for a guard. When you run backwards into the defence you never get called and just look at the guard with your arms out to receive a pass.Marking contests are hard to adjudicate on. The one that still gets me (not sure I have a solution) is when an opposition player deliberately stands between a player and the contest so that player can’t compete properly and has no intent to contest the mark. That has been used against Jack for many years ( and i am sure others) especially when he was at his high flying best. Dylan Grimes is very good at it.
The defenders in afl shape as if to mark but are just setting a screen for the third man to float in front. I think technically it’s a shepherd outside of five metres but rarely called.
