I would have gone up to the coach after the game and said, "You suck". When he started to react, I would interrupt and say, "Coach, I was just telling you what your player said to me at the end of the game. Now, I think you should say to him everything you were going to say to me."
Also, I would have made sure the player got grounded until he was 21 by his parents, became disqualified from ever getting a drivers' license and had all his scholarship offers withdrawn. I'd also make sure he had to share a room with his sister and be forced to go to Barry Manilow concerts.
There - that should be enough punishment.
