We also heard the presentation 3 years ago when my son was a freshman. I thought the information was very helpful. We walked away thinking the general message was "if you want to play there's a place for you" which I DO agree. (Unless you have zero talent)
He did say, first question to ask is whether they are offering the official visit. Fortunately son was smart enough to realize this wasn't appropriate in many of the conversations. It was interesting though to note that those who were REALLY interested said right off the bat, "we want to bring you out for a visit", without son HAVING to ask-but that's a side note.
We were never contacted by anyone to sell us anything or any service. I appreciated the information, but maybe the talk has changed since we went.
