I know if we ever get to the end of a game and need it, people will get out the pitch forks, but here goes. Use a to when the flow of the game starts changing in the second half. Get the coaches to come up and tell you what they are seeing on the field and how they would like to adjust (15 sec time limit). Then call the kids in and get them focused, pumped up and share what you are seeing and how to correct it. MORE COMMUNICATION has never ever hurt. In game communication is a must.
