This still happening? This is the age where kids really starting dropping off -- 6 days a week of soccer could push many over the edge!
They shouldn't be doing HS and club. It's way too much. Some states restrict club/HS sports in the same season with good reason. This is really for the kids who aren't playing HS or maybe some older 8th graders with no fall teams to play on. Anyone trying to do both is setting themselves up for exhaustion and overuse injuries.
