I am sure we all know or have one HS student. Trying to keep the bulk of them involved in a year round program is very difficult. The majority of these kids are super streched for time and another long term commitment isn't realistic. I am sure many teams don't have the luxury of well developed off season programs. learning in the offseason does work, this is what provided us with the tools and knowledge necessary for the Mecunum drive. We didn't start at zero on week 1. However the relatively small offseason group widens the gap with the in season group creating an inefficient learning environment. Resulting in the smaller group shouldering much of the build season load. Extending the build season will not change the competitive dynamic of the game as much as the opportunity for less experienced team members to learn.
