On a throw in by the blue team, a blue teammate, with an opponent right behind him/her, in anticipation of the ball’s receipt, turns just as the ball is thrown to a place behind and to the side, making contact with the opponent and “pushes off” the opponent with his/her body then runs onto the ball. The player does a “quick turn” with the clear intention of pushing off the opponent with the shoulder or body to seemingly gain an advantage. Comments? Is it all fair in love and soccer or is there a more nefarious
I asked my husband’s niece who uses this play and she said that she is coached to do this. They want someone right behind them so they can use this tactic to their advantage.

USSF answer (April 17, 2009):
Turn about is NOT fair play in this case. If this happens before the ball is released, the throw-in, if subsequently completed, is taken again and the thrower’s teammate should be warned not to repeat this action. If he or she persists in this behavior, the correct remedy is to caution the player for unsporting behavior and retake the throw-in. If this happens after the ball is released, stop play and restart with a direct free kick for the opposing team from the place where the infringement occurred.
