I don’t know anything about softball but generally speaking women’s sports move along foster the men’s because it’s more competitive for the coaches (in most sports there are fewer men’s teams to comply with title IX).
In every sport, the top athletes get offers right away, but few coaches give all the offers at that point.
The other thing that happens is a trickle down effect. For example, NESCACS are not interested in settling things too soon because they want to see who dropped from the Ivies.
Regardless of timing, make sure to cast a wide net. Find great fit schools that are athletic safeties and pursue those in earnest. There is a lot of growing left to do. Maybe she will decide she’d rather go to a school even if she is not on the team, or she will decide that a walk on spot or a team she can grow into is good enough, or maybe she will be happiest being a starter off the bat. Keep the options open.
Still, no matter which direction she chooses, the number one priority should be a school she loves and can see herself at even without the sport.
