The best backhand of all time and there is no doubt at all about this, was Jimmy Connors, he could do anything with it. Flat, topspin, slice, lob, drop shot, power, placement, so penetrating, clean winners or never miss, take it on the rise, disguise it, block it, angle it, reverse, return of serve, hit it harder than anyone before, during and after his career. Shall I go on?!
I love some of the one hander topspin backands out there now and over the years, Rosewall, Edberg, Federer etc, but i'm afraid two handed topspin backhands are just stronger.
Borg, Wilander, Agassi, Nadal, Djokovic and Murray.
And of course the greatest of all time 'Jimmy Connors'!
