I'm guessing more girls stick with soccer than the % of boys that do.......they don't have football to take athletes out of soccer.....basketball is probably mostly viewed as "only for tall girls" and yeah, softball includes a different type of body type than baseball does on the boy's side.
Softball needs some major rules changes. Limit the ace's frequency with how often they can pitch. Softball today is what MLB is trending towards - strikeouts, walks, and homeruns ONLY. Ugh.
And they've got some big ole girls at the plate that make David Ortiz look like a spy shortstop.
Girls also have a lot more gymnasts drawing them in than on the boy's side, I assume. Sort of the opposite of the basketball girls, in terms of size. But I bet if you took some of those gymnasts and raised them playing hoops, they'd be great lil point guards. The 6'5" ladies aren't the most coordinated. A lot fewer Wilts and Shaqs in the women's game - a lot more Shawn Bradley types, imo.
A shorter, better athlete could run circles around them on the court.
