So, I'm watching a YouTube video of Roddick/Federer (2007 US Open) and Agassi was the guest commentator to start the match. McEnroe noted that Agassi's arms on his backhand (when he was playing) seemed very relaxed until he made contact, while Roddick's seemed stiffer when he takes it back on the backhand side, making it harder to generate pace. Agassi then elaborated: "No question. He has definitely a fundmental issue with his.....He hits the ball with his left hand (he has weak right grip), and he pushes it back in with his left hand. The harder he tries to hit it the more it looks like he is just sort of rising up on the shot. I hit primarily my backhand with my right hand until I make contact, then allow the racket head to come around at the end". McEnroe then asks if he can make that adjustment or is too late. Agassi responds, "Um, I'd have to watch him give that a go, it comes a little bit more naturally to some than others, no question. The best backhands in the world, are the ones where the racquet head is up, there's a strong right hand with it." I'm coaching my 7 year old son (who shows good ability). Is this what I should try to instill in him?
