D gave up vball and bsktball in HS to focus on softball. The time commitment would have been too much as our district had away games 2 hour bus rides away. There were a number of girls on her sb team that got scant PT, but they were happy in their roles and enjoyed the camaraderie. Some of the most memorable times for the team were the long bus rides. Sounds like your D.
I think if your daughter has any aspiration of playing sb in college, even D3, she’ll need the travel ball rep’s. Unless your HS plays in a very competitive district/state, the talent will be very uneven in HS ball. As a junior, to have any shot at recruitment, you will need to hit the showcase/camps hard this summer. You need to contact schools she’s interested in asap through their online recruiting questionnaire and send emails directly to the coaches with both an academic and athletic resume, along with skills (hitting, fielding, throwing, pitching (if applicable)) and game video.
Walking on is a possibility, but most teams will have tryouts because of practice rep and cost limitations. As an aside, D was able to pick up vball again in college as the sb team banded together to be an intramural vball team. They had fun and did reasonably well since they were all good athletes to begin with.
