Let's stir this baby!
Cali, Alaska, Ohio or wherever, it all starts with ATHLETICISM - as in the genetic "gifts" a kid is born with. Just like singing, you have to have something to start with.
So you gotta be in the athletic pool FIRST. Being athletic will not guarantee success, but lack of athleticism WILL guarantee a lack of success. If you could develop athleticism, every girl would be sub 2.7 to first, and pitchers could "practice" their fastball up to 70 mph! But those athletic kids who don't work on their game skills will be just average athletes up to a certain age, then get passed up by their peers.
Look at the OSU kicker - a sokker player. And star running backs are usually track stars trained to carry a football. Athleticism, then specialized training.
It's not really a complicated formula. In California, the girls are NOT more athletic, there is just MORE OF THEM! Just like D-I vs D-IV high schools in Ohio, D-I has a much bigger pool to draw the athletic kids from.
More bluntly, it's like race horses. All the champions have certain physical abilities and attributes that they were born with, and superior, specialized training made the best of those attributes.
So, if your DD isn't athletic, but loves softball, is she supposed to quit and take up piano? If you ask that, you missed the point entirely! Talent and ability have no connection with "love of the game". I dearly love baseball, softball and basketball - but 10 minutes on a basketball court with my 16 yr. old would kill me!!
Bottom line - if your DD truly loves playing the game of softball, SHE will be the one pushing YOU to help her get better. If it's the other way around, there's a big hint being ignored...
