answer... middle school sports are a joke in general. however, the practces and games are weekdays after school, no conflics w Club in case your son wants to do both club and middle school (recommended)...

so no choice needs to be made...

A good plan would do both in 7th, have a great middle school season so the coach can recommend your son to play up to JV as an 8th grader (still have school experience etc and lose the modified middle school program)
