The Storytelling Problem in Tennis

Tennis is a totally mental game. What determines whether somebody wins or loses in tennis is almost never their physical ability. Vic Braden was this world famous tennis coach and he found himself being able to predict when players were going to double fault, which almost never happens in a match. He went back and looked at all the videos and he was looking for little things here and there that might be tells and he couldn't find anything. And it's almost like he's able to see inside these guys heads. So like there could be a whole book written on that topic and I'd be fascinated.
