hi - good luck this weekend! My son is also attending his first showcase this weekend, so my advice comes from the viewpoint of a dad who hasn't been through this before, but I'll tell you what I will advise my son and then you can see what other advice you get. First, I'm sure that the coaches there would certainly like to talk to you. It is a chance for them to see young men in person and see how they carry themselves, communicate, etc. If you want to meet a coach, look them in the eye and introduce yourself with a firm handshake. Be polite and respectful of whatever advice/information they give you. Think through your questions in advance and think about what your goals and interests in the future are so that you can answer their questions intelligently. Try to find out what schools/organizations are going to be there, and if you have particular interest in any of them, do some research on their websites in advance so that you can ask intelligent questions that will give you the best information on their programs that will help you in making decisions about where your interests may lie. Also...have a good time! Don't put too much pressure on yourself.
