I think that event is run by Oscar Miranda who has a good reputation. Full disclosure-I dont know anyone personally who has gone to the live or virtual showcase. However I know that D1 coaches (but there are more coaches from other divisions), even at least one Ivy League Coach had attended past live showcases. Join this free FB recruiting site:
https://www.facebook.com/groups/808424032556193 or search for College Tennis Recruitment Video Group on fB. You can look for posts by Oscar Miranda there and college coaches replies to him. Also his Sept 30 post showed part of a spreadsheet of players he had placed including players at D1 (mostly MM for guys).
Are you looking for a son or daughter? When do they graduate? On the CTRV free site, recruits can post video, UTR, desired major, and available budget, and receive some replies from coaches. Most are d3, NAIA, or D2; there are D1 coaches that are members of the website but if they reply, I assume they do it via private message. However, it is a tough time to be a recruit. Lot of players in the transfer portal-players looking for 5th year, players whose teams were cut. Some teams have no openings except walk ons for 21/22 as their seniors are returning or the spots are filled by graduate transfers.
