I would not worry about the 2019 team. Competition is not strong at this age and the entire core team is back. The game is controlled by your strongest 10 kids. A few purple kids will slide in to replace some of the 2020's and a few new kids will do just fine as well. This team will continue to evolve over the next two years. Many talented kids don't start playing lax until 7th grade so there is an opportunity to pick up a few more strong kids in the coming years (new kids or transfers).
