Here in France, it's also "non, non, et encore non"
We doesn't allow receivers pivots and angles too. The offense coach can put the stick anywhere in front of the receiver (about 90°), but can't touch the WR to help him to find a line for running. No turn and burn too, if he complete the pass, the ball marker is removed and the board is turned on. The offense coach never touches the wr figure.
THe defense coach can pivot any free player to intercept (pivoted in direction of the ball first, if he touches first : interception) or tackle (touch the wr after the pass completion).
if the defense player tackle the WR between the WR original position and the ball marker : it's a defense fault.
It helped us to make the stick rule more fair for defense, and balance the passing/running game on offense.
