Why are there no U8 evaluations?  
SMLC feels its too early for kids to experience any type of evaluation process at such a young age.  Teams are formed based on grade and will likely be limited to 2nd graders. 1st graders will once again play in SM's house league (1 practice p/week and 2 games against 2nd grader SM teams).
Every parent coach in the spring season is a volunteer.  Please give them a HUGE thank you when you see a Wolfpack Coach.

Every Wolfpack coach is required to participate in the "Positive Coaching Alliance Program (PCA).
SMLC boys and girls coaching staff consists parent and non-parent head coaches who have HS, College or Professional lacrosse backgrounds. We are extremely fortunate to have a very talented group of coaches/volunteers who not only pass their knowledge and passion of the sport along to the kids in our community, but they do so in a manner that promotes the basic principles of competition, respect, and love for the game.  

Team Placement:
Player Evaluations: Evaluations take place in January.  No Cuts - all registered players are placed on a team.  Player evaluations help us create balanced teams within age groups. 

Rosters are published in late December/early January.

Earning a spot on the “A” team requires a full time commitment for practices and games over other spring sports.  “B” Teams provide a little more flexibility to accommodate other sports or weekend conflicts (playing time is at coaches discretion if attendance becomes an issue).  If your son cannot make a full-time commitment to lacrosse in the spring, then the B team is the way to go.                

Coach Evaluations 
At the end of every season we ask our coaches to submit evaluations of their players based on many different factors including hard work, attendance, attitude and talent. 

Practice Schedule: 

SMLAX sets the practice schedule for each team in January, after players are placed on a team.  There are always a few requests to switch to a different team based on specific conflicts.  While we try to limit these requests, we do our best to accommodate them when possible.
