Is it doable for you to travel for one showcase/year? This is what we try to do with my high schooler. It will most likely provide a professionally filmed bp for your son to retweet. I've noticed that some of the bigger recruits in our area will retweet highlights from a showcase or a mention in a tourney tweet....but they'll also retweet videos of their teammates. This seems to give an idea of the kind of teammate your kid is on and off the field and helps to add a little content to their profile page. It's really cool to see the high schoolers building up their friends. My son and his friends do this on instagram as well (add a teammate's post to their story).
