Will do. I've heard it's good to send them a link to a skills video when you email them to introduce yourself. This seems logical to me. Any thoughts on whether this needs to be a professionally produced video or what the exact contents of the video should be?
Rich at Play In School (PIS) regularly posts on this site. His business is professionally producing videos of players, mostly baseball and softball. Check out his website and view several players, especially position players. (keewartson is on there somewhere). I have seen several Youtube videos as well floating around. You can even do your own website for your son with his baseball resume, video clips, contact information, etc. A google search (ie. "baseball recruiting video") will also bring up many players that have done this.
To be honest, a college coach isn't going to recruit from a video, but it could drum up interest. keewartson attached his video link with all college coaches he corresponded.
Send these coaches his playing schedule, too. If he is only playing high school ball or legion, send that schedule to local schools that can easily make the trip. (And don't discount fall ball. There were 2 local D1 schools at keewartson's game two weeks ago).
