Anyone who runs and reaches for far out balls has that shot, including Roger. It's not really unique. The fact Nadal gets it in court so often is just a testament to his animalistic ability to run like mad and his luck as well.
Nope, Nadal, Djoker and Muzz have an uncanny ability to put their extreme-reach defensive lobs right back to the opponent's baseline.
Roge rarely puts up defensive lobs these days.
