Absolute crazy rambling, but really curious about these ideas and maybe will spark a good discussion.
Allow pitchers to throw overhand. As I was reading the comments in the other thread about such a large pitcher shortage, why not allow girls to throw overhand? Throwing underhand takes such a massive time invest that gets zero benefit with any other position or sport. It's also the most efficient way for the body to actually "throw" something. There would be very few, if any, that could actually throw the ball harder overhand. Maybe make some new rules or stipulations for it, but why not give it a go?
Enact a new bat standard for 14u and above. Almost any fully grown girl can hit the ball over a 200ft fence. At 15u most all baseball goes to the BBCOR standard. That's -3 bats with a .50 BPF. The game flat out changes. Suddenly that 325ft corner becomes a massive challenge. There are very few HR's in HS now. Most teams have zero HRs after a season. Even now in LL they have a whole new standard that just started this year. So why can't softball have something similar? Let's say mandate a 1.0 BPF, -8 standard at 14u+. Baseball has gone through 2 new standards in just 7 years, so no matter how much parents complain, it's still VERY doable. For softball, bats are hotter than hell. Baseball massively deadens their bats though at the same time the field size massively increases. You can argue the differences between boys and girls, but the field is always the same for girls from 8u to college. Go to the baseball boards and you'll still see regular posts about, "How does my son go from -10 to -3 in one season?" You'd see that here too, but the true hitters will still hit.
