Final answer:
The statement in question is not completely correct; a whistle is not always needed to restart play for corner kicks, kick-ins, or goal throws. In soccer, these set pieces do not generally require a whistle, with certain exceptions like specific infractions or game stoppages where the referee must signal for a restart.
Step-by-step explanation:
The statement "There can never be a corner kick, kick-in, or goal throws without a whistle to restart" is not entirely accurate as it pertains to the rules of soccer. Generally, most restarts in soccer, including corner kicks, kick-ins (which are not common in formal 11-a-side matches but may be seen in indoor or futsal games as a replacement for throw-ins), and goal kicks, do not require a referee's whistle. The primary instance when a whistle is necessary is after play has been stopped for some infractions, fouls, or when another stoppage has occurred, and the referee needs to signal the restart of play. However, during the regular flow of a game, these set pieces usually do not require a whistle.
For example, once the ball goes out of play over the goal line by the defending team, a corner kick is awarded to the attacking team. The player can then take the corner kick without waiting for a whistle. Similarly, goal kicks can be taken as soon as the player is ready, without the need for a whistle unless the referee needs to manage a situation on the pitch. It's important to follow the guidelines set by the referee, and if there is uncertainty whether a whistle is needed, players should look to the referee for direction.
