Murray playing so bad with his 20KPH groundies he makes any mug look good
All the matches I have seen of him since the beginning of the European clay season (admittedly, no more than 6-8 matches, but on different surfaces) he has been predominantly 'pushing' the ball. He'll be going backwards next year unless he goes back to being a little more offensive.
We should be appreciative of Federer though, because we will never see anything like him again. The fact he can still compete for slams ever after the erosion of his physical skills is really a greater testament to the natural talent he has than the period of time when he was dominating the tour.
