Different rules for 9/10 and 11/12 causes confusion.Rule changes this year (drop off on goalies in possession,sub windows) have added to it.Our club provides the official rules to every player and makes them and their parents read it.Obviously a lot dont and still look stupid complaining about refs on weekends.I wish some clubs took it a bit more seriously though as seeing kids lined up to play and clubs still scrambling for refs or people out there who have no earthly idea what they are doing is a terrible look.
