Tennis is an individual sport where the players' moves and cunning are displayed for their opponents and the fans. Though tennis players have coaches, until recently, a player could not be coached during a game. There have been many instances where a player appears floundering and looks up to the coach's box while the coach remains stone-faced; if a player was caught receiving coaching during a game, it was a violation, affecting the score.
I'm watching Wimbledon, one of the four Grand Slams in tennis. It's unreal and a bit voyeuristic to see a player come undone without input from his coach. Even in other individual sports, such as track and field, the runner can receive guidance from his coach. So what made tennis so special? It was simply a matter of tradition.
