I think he can do a little better on the return. he still drops it a bit too short at times. nobody on the planet can pass as well as he can so why not jerk them around a little bit.why not drag them into the net a little more. bring them in and then ruin them. he can make more effective use of that slice which seems to be improving. a short slice can bring them in. he also does not use the topspin lob enough. that topspin lob comes very naturally to him since he already imparts heavy topspin off both wings. some of this will start to take their rhythm away. it will keep them on their toes and keep them guessing. I will have more to say about this later.
