Angry Coach Problems

Speaking from my personal experiences with multiple coaches here are some of the worst things that have happened with a frustrated coach.

1. Having them throw all of their stuff at the wall, before our after game team meeting.
2. At a team meeting, having them come in and say "I was taught that if you have nothing nice to say, don't say anything at all" and then walk out of the change room.
3. Running at practice every time you do something wrong!
4. Having the coach say in a mid-game situation that if we are not going to listen to them, than we can coach ourselves but until then we are on our own.
5. When a coach has made an unrealistic goal for a certain drill, which means if we don't meet that goal we NEED to run!
