Have an 07 or u14 whatever you want to call it, interested in playing U15 next year instead of highschool and or prep school. Is u15 5the route to take? Or prep school?
Have your bender play both. Most U15 is a half season that ends before thanksgiving, and high school/prep starts just after thanksgiving. This is what every kid on our HS varsity team does. If your bender is going to play prep next year, figure out if he can play U15 half season, or if he needs to play a fall sport at the school.
