They are a pretty big deal.
General information is this: Teams are by Schools and divided into 2 classes -- Big Schools are the Class 6A and 5A schools and the Small Schools are the 4A and below. All teams are "Dad coached", that is the school coaches are not allowed to coach the teams. Of course, coaches sit at the back of the EZ and comment from time to time -- but they can get in some hot water depending on how far they go.
As for the game -- 45 yard field. Possession starts at the right hash. 2 20 minute running halfs -- with a 10 minute half -- so games are 50 minutes. Games start on the hour -- so another 10 minutes between games. The schools running SQT or State Qualifier Tournaments. One school will host 16 teams -- 4 pools of 4 teams. 4 teams play 3 round robin games each. Each pool winner advances to semis. Two finalists qualify for state tournament.
As for officials -- Pool play typically has 2 officials -- one on each side line. We call fouls, player down and FP. We do not handle the ball. Players have to spot the ball. Officials are paid $25 per game. For Semis and Finals, we use a third official -- back judge -- but pay goes down to $20 per official.
State Tournament at the end of the year increases the number of officials, but reduces the per game fee.
