Shame on you to even speak about a team of 7/8 year olds in terms of how good they are...bad enough this happens with 9 year olds...shouldnt you be asking whether they are having fun and getting better at lacrosse? My son plays on the 2nd Grade Jesters Team...the team has two committed coaches who are great with the kids, the kids are learning and having fun...they have had something like 15 practices, 5-6 games...coaches work on skill building as well as some more advanced concepts and ALL of the kids (the stronger and the weaker kids on the team) seem to be benefiting from the practices...I have only heard possitive things from the parents on the sidelines as well.
Just out of curiosity when you say "how good can they be" who are you comparing them to?...some ultra-elite 7 year old team who are being recruited by D-1 Schools?
