Not all of them do, but a ton of the skill kids do, in all classes. Then you throw in all the summer basketball that goes on as well. It makes for a pretty busy summer and most of your 7-on-7 have to plan for that.Well in that case...
Dont kids play 7 on 7 all summer though? Plus, not all kids play both sports. That's not to say a spring season wouldn't be a good thing.
