I think that in the case of Colfax girls BB and VB it is very much about the coaching and work the girls before high school. The High school HC can focus on more advanced things because by the time the girls hit HS fundamentals and such are second nature. In Colfax junior sports is deadly serious while getting a hug turnout. The system doesn't just develop players it develops high quality Youth and AAU coaches and coaching systems. And like I said on another post, well over half of the coaching a player will ever receive happens before high school.
However, that same type of youth sports system wouldn't work in Pullman. Pullman has a fine youth program and some good AAU teams but it isn't as focused and well structured. Pullman is a little less isolated and a little less homogeneous of a population. There is so much more going on and the population is far more transient. Pullman, I think tends to get a little more talent over time than some other schools its size due to the type of community it is with the Universities and technology development incubators. Pullman has a good sports program but what is amazing is how good they are in so many sports, not the #1 program but top 20% in so many sports. And not just sports, everything from Band to 4H to the astronomy club. The school and community really focus on kids getting as much out of the passions and bliss as they are able.
Two very different communities with very different sets of advantages and disadvantages, yet each has developed a system where they can take full advantage of advantages and limit the impact of their respective disadvantages.
I'm sure Lynden has yet another system with like goals to explain their amazing success, as does Prosser, as again I'm sure does Reardan and Royal and...
