Two of the greatest qualities in this country are freedom of choice and association (let's hope they endure). Recruiters are, for the most part, not provincial in who they go after for their team and kids are not usually provincial in determining which school is the right fit for them.
To answer one question, yes my son had offers from midwest schools (as well as other ACC schools) but this school offered the best combination of academics, baseball and overall fit for our situation.
To answer anther question, playing in the top level tournaments (WWBA 17U, Jupiter, etc) and attending the Stanford camp played an important role in the process.
