 Steps up to the line again, double fault. Now he's pissed. Now he's really amped up, so what does he do? Tanks the ball like three feet long, game over. Set was pretty much done. I get on a video call the next day. So watch a little bit of video. I'm like, okay, does this look normal? Well, maybe I was a little tight. But that was so profound for him because he didn't even think there was any alternative than to serve even when you're tight. So the difference between when it's not going where they want is in their physiological state. It's because your heart rate's different. Your breathing is different. Your muscle tension is different, which changes the speed and power of your movement, which is why the ball misses. Changes finite motor control, changes all of those things.
