Just finished a great tennis conference featuring, amongst a host of others, Brett Hobden, an enthusiastic and knowledgable tennis pro.   Brett works with lots of players, especially juniors.  I asked him if her ever uses video analysis, and he enthusiastically replied “Yes!”  One use that he immediately identified was the “problem” player who doesn’t seem to listen.  He says he sits him (or her) down and goes over the video of a match, point by point!   The  player invariably becomes much more teachable, and progress can resume!
