Actually I think it's more likely kept ME out of rehab! Great for family togetherness (even though we don't sit together at the games, we still ride there and back in the same car), lots of social interaction with other baseball parents (and someone to talk about in the car on the way there and back), AND a great excuse to leave work on time (OK, sometimes even early!) 4 or 5 days a week!
The reality though is plenty of kids who are heavily involved in sports still get in all kinds of other trouble - there are parents on this site who can tell you some sad, scary stories - so don't assume anything. The pressures are still there and sometimes for our boys the pressures are magnified by the added pressure to do well on the field - it can be tough to handle and unfortunately some do choose to deal with it chemically. And it sure doesn't end in high school.
