Probably the hardest thing for them to understand, especially the kids we have who play football, is that lacrosse offense isn't based on set plays. It's more prudent to just have an offensive scheme. Being creative with the ball is the best way to score.
I have one kid that has played before, really. I have two kids that played, maybe, one season, years ago. Ninety-nine percent are brand-new kids. First time they picked up a stick was three weeks ago.
