Very true. Typically, success breeds more success. Just comparing BB and BD a little since it was brought up and their comparable access to clubs, rtc's, clinics, etc.
Look at what Brownsburg has done since 2014: 147 dual wins and all types of team accolades, 50+ qualifiers, 40+ medalists, 6 state champs (probably off a little somewhere)
Ben Davis since 2014: 60ish dual wins, 8 qualifiers, 5 placers,1 champ (probably off a little too)
The BD kids have similar opportunities due to their proximity to Brownsburg, Indy, and so on.Just because the opportunities are more accessible to certain schools of similar size in certain areas of the state, some schools just aren't going to have that same type of success.
Different schools = different kids, as well as different coaches, parents, admin, etc., with different interests and goals too.
Some kids/parents may choose to pick up and move schools to pursue those opportunities at other places because they have the means in which to do so. Other kids/parents may choose not to, maybe they don't have the means to do so either.
I am not sure if there is a one size fits all approach to balance or fix things. Mat time, lots of exposure to multiple coaches and practices partners, camps, clinics, off-season events, setting goals and working towards them, seeking out tough competition, making sacrifices.....there is so much to do in order to reach that pinnacle.
