There are so many youtube tennis recruiting videos it is almost impossible to weed through them all. And the vast majority of them are from foreign students looking to land a scholarship at a DI school.
It is helpful to have a youtube video, specifically with match play posted that you can alert coaches at schools in whom you may have interest. Many Division I schools already have their recruits picked out but as a Division III coach most of us have rather limited recruiting budgets so any information we can find online proves most helpful. If you have a list of schools in which you are interested, I would highly recommend sending the coach an email with your information. I find it helpful when a student sends a link to a youtube video, especially if it includes point play or match play highlights. Watching a video with perfectly fed balls with the student hitting the same stroke from the same position on court is nice, but not realistic.
Hope this helps
