My backhand breaks down against pace. I think that I have the racket back early and I just don't swing soon enough, but I don't have video so it's hard to be sure. I am looking for specific drills to do with a partner or wall (I doubt there are any as the ball usually doesn't have pace on it) to work on this. Of course I can just rally with a partner and ask them to attack it, but this tends to get boring for them if I keep missing... Thanks.
