If you have a good club coach/recruiting director and your dd has been consistently sending emails, the schools who call/text/email on June 15th shouldn't be too much of a surprise. My dd got a very generous offer on a call on June 15th that was tempting to just accept on the spot, but I would recommend all recruits take the official visits through the fall to see the team play and practice with the season and school in session. See how the coach interacts with players, see how many players don't get minutes in games, see how many players are unhappy, get a real understanding of the resources available to the players, etc. My dd went on a few official visits and had a few more scheduled, but cancelled some once she went on a visit that just felt right for her. However, I am glad she went on a few to see different schools/programs. If you are going on an official visit, an offer will be presented and a parent should be there to understand the financial side of things and ask questions. Lastly, it is a red flag to me if a coach gives your dd a short timeframe to accept an offer. It can be a stressful time, but try to let your dd enjoy the process.
