I seriously can't comprehend all the assertion that, "Well, obviously he won't beat MURRAY..."
What in God's name has changed about Murray beyond having a different number next to his name, that's suddenly going to turn around a one-sided rivalry that has, if anything, become even more one-sided in recent years?
Now, Novak has been well off form, and that's got to feel good for Federer and his camp. And maybe it'll be a little surprising if Novak can right the ship so quickly. But if peak Novak somehow does make an appearance? Of course he can beat Fed. What if Nadal somehow turns back the hands on Father Time's clock? Not expected, but if it happens, of course he can beat Fed. There are even a handful of talented, powerful, shotmaking guys from the field who, if they catch lightning in a bottle, are capable of beating Fed.
But Murray, no matter how well he's playing, has shown over and over again that he simply doesn't have any weapons with which to trouble Federer over a best of five. Andy's patience and consistency is a real weapon against the field, but against an all-time shoemaker who's seen it a million times, it's just target practice.
Fed doesn't need to avoid Murray to make a successful run, and in fact, probably hopes he gets Murray's quarter of the draw. Murray absolutely has to avoid Federer, however, or it's game over.
