My 2017 went his Jr and Sr years, 3 and 4 years ago. Back then, it was awesome. It was a 2 day showcase back then and there seemed to be about 50 colleges (maybe more). I thought it was extremely worth it as my son received several offers from local D3s immediately after each day.
HOWEVER, My 2020 went last year (Jr year) and it was different. You picked only 1 day (2 days offered, pick 1). There were not nearly the colleges there. Maybe 15 on the day we went. Completely different in terms of exposure. I don't know if that was just a bad year or if the coaches simply stopped going but what was once a sure fire showcase is now something we're considering. As 3and2 said, we'll probably go if we have no other options since its fairly local and he gets local coverage. Maybe it was just a down year or the coaches came dressed as civilians.
There is no write up on the player, but you will get all their measurables. Mainly regional coaches from WI, MN, IL. It is a well run showcase. Like I said, we really liked it before they changed format from a 2 day event to a 1 day event.
I thought this showcase was definitely used more by the D3s in the region, which is good during the process of getting your name out there. As I said, very good several years ago, not sure now. There are still around 15 coaches in attendance. That's still not bad for the money (I believe around $275?). Its just that there were a lot more before. Hope that helps.
