On a corner kick, may offensive players start from a position inside the goal (beyond the goal line) and then run out (in front of the keeper or to other positions) as the ball is being kicked?
I recently saw this employed, where one offensive player began inside the goal, then ran out in front of the keeper as the ball was being kicked.
USSF answer (January 13, 2011):
Other than those putting the ball back into play, players are required to remain on the field of play. So no, the tactic you describe is not permitted.
