On the topic of player meltdowns, I am going to venture a guess that there are coaches and adults in the players life that have contributed to allowing this behavior. I'm not excusing it, just think that coaches and leaders of these kids need to step up as well. The kid was thinking much more of himself than the team. More than likely he has learned that from coaches who have put winning the big games over taking the time to discipline this kind of behavior. So, many times these kids are being selfish, just as there coaches are being selfish by not helping the kids by making them accountable for their actions.
Who was the woman trying to comfort him while he was throwing his tantrums? That was embarrassing to watch. I know nothing of either teams but was watching the game with my younger son who plays middle school ball. He commented that the kid should have been in the huddle with his team encouraging them after he fouled out. He was not a team player.
