“There’s only one microscopic weakness in Federer’s game which is the inefficient one-handed backhand which cannot generate power “
I’ve never seen Fed play a better match than today and it was because I’ve never seen Fed have so much power off the back hand side. He was just ripping his backhand.
If his backhand stays this good, Federer could win many more grand slams.
Federer is doing the best job of hitting that shot which has ever been done but it’s still an inefficient shot, sort of like lifting a stone instead of using a lever; he’s moving his arm one foot to move the racket head one foot. Again I have no picture of anybody exploiting that on grass.
