For a team to have success it doesn't always mean making it to state. It could be contending for conference championships or even dominating a few local rivals. It also could mean getting to the play-offs and advancing, but not necessarily to the state championship. The good programs, regardless of the sport are build around winning.
What you are describing is the individual success that is going to lead to more and more team success. More kids out for any team is good as it will create competition for each starting spot.
