It's hard to be a jerk...er...coach
The point I was trying to make was "Be patient. Don't just throw the disc up and expect your teammates to bail you out." It's not an easy thing to tell someone, so when I caught the swill, I immediately threw it away. It was a statement, "That's not what we wanted." I'm afraid my young friend heard a different statement, a "You must be perfect" sort of statement. That's not what I meant. And when we exchanged the loud words that's what I tried to explain.

By the end of the game, he had stopped throwing it wildly.

Did I win or lose? I got the results I wanted. Was there a better way?
