If you are a high school tennis coach, or for that matter, any coach  responsible for four or more tennis players at a time, here’s a video with some great ideas for drills.    Mea Culpa:  This video was not planned, and especially the audio was not planned as the acoustics of the indoor courts were not the best.   We decided to film the drill at literally the last minute as our attendance at the conference was for other reasons.   Enlarge to full screen for best effect.  We’ll work on getting a written description of each drill and will publish then.  If you are in a hurry, send an email to info@box2325.temp.domains.  Enjoy!
